Wobble Wedge® plastic shims can support up to 2,000 lbs, making them perfect for holding heavy loads like stone countertops, wooden window frames, and heavy porcelain toilets.

Need more proof that Wobble Wedges are the best plastic shim for construction projects? Below are some of our customers favorite uses for Wobble Wedges in residential and commercial construction environments.

Window Framing and Installation

Even with all of the care, measuring, and leveling in the world sometimes windows just won’t sit level in their frames. Use a standard size or BigGap™ Wobble Wedge, depending on the size of your gap, to accommodate and level the window before framing in and finishing the window. Windows that slide open or closed on tracks must be especially level for the sliding mechanism to work smoothly.

Stone Countertop Installation

Multiple cabinet units installed side-by-side are rarely perfectly flush all the way across the top. In addition, stone slabs contain natural imperfections that can cause them to wobble or rock when installed. Sometimes, even a Mini Wobble Wedge is enough to sure up the gap and get the countertop to sit perfectly flush. Use a flexible plastic Wobble Wedge between the stone and the cabinet top.

Level Stone and Concrete Pavers, Blocks & Steps

The buck doesn’t stop there! Use BigGap™ Wobble Wedges and standard sized Wobble Wobble plastic shims to level stone and concrete pavers, blocks, and steps. Finish up a new set of exterior concrete steps with perfection by compensating for any gaps with Wobble Wedges. Install a new stone paver patio free of tripping hazards by putting plastic shims under any of the pavers that rock or wobble.

Fix a Wobbly Toilet

For more than three decades Wobble Wedge has been earning its reputation as the best toilet shim among professional master plumbers and residential handymen. It couldn’t possibly be easier to use. Simply slide a flexible plastic Wobble Wedge under the rim of the toilet and use an exacto knife to trim away the excess. Wobble Wedge toilet shims are available in white, clear, and black. Choose the color that blends most seamlessly into the finished environment.

Level Large Appliances on Uneven Flooring

Last, but certainly not least, deliver homes with every last detail of perfection by ensuring all of the large appliances are properly leveled. Use BigGap™ Wobble Wedges to level and balance washing machines, dryers, dishwashers, and refrigerators.

How to Use Leveling Wedges

Between uneven floors and self-assembled furniture the reasons for items to rock or wobble in your home or business are unlimited. Leaning bookshelves, wobbling tabletops, and rocking appliances can compromise aesthetic, comfort, and safety. To quickly and professionally resolve issues with wobbling furniture or appliances use handy plastic leveling wedges like Wobble Wedge. For more than 30 years Wobble Wedge® has been the proprietor of the world’s best leveling shims, available in flexible plastic and rigid plastic, and in a variety of sizes and colors.

What is a Leveling Wedge?

The concept of the leveling wedge is a simple, but powerful one. A small triangular sliver of strong plastic material that can fill the gap between your furniture or appliances and the flooring material to create lasting stability. A level shim gradually increases in thickness to provide a universally convenient solution for gaps and wobbling. Additionally, Wobble Wedge shims possess patented interlocking ridges that allow users to stack and combine wedges to fill any gap. Flexible plastic Wobble Wedge leveling shims can be trimmed with a utility knife once placed in their location so the excess wedge material is not visible to the naked eye.

How to Use a Leveling Wedge

Using level wedges is an incredibly easy process. To determine if your furniture or appliances need a level wedge simply place both hands firmly on top of the object in question. Gently shift your pressure from one hand to the other to see if the item rocks or leans. If the item in question shifts under your pressure it is resting unevenly on the ground. Place a level on top of your furniture or appliance and rock it very gently to find the level point. Once you have identified how to make the item sit level, use Wobble Wedge plastic leveling wedges to fill the gap between the bottom of the item and the flooring material. Stack and combine wedges until the gap is completely full. When you remove your hands from the top of the furniture item or appliance it should sit stable on top of the plastic level shims.

Flexible Plastic vs. Rigid Plastic Wedges

Depending on the flooring material and the item you are trying to level stipulates whether you should use a flexible plastic leveling wedge or a rigid plastic leveling wedge. Furniture items placed on hard flooring material are best served with a flexible plastic leveling shim. Flexible plastic shims will grip hard flooring material surfaces and won’t slip or slide under pressure. Appliances or furniture on soft flooring materials such as carpet or rugs are best benefited by a rigid plastic leveling wedge, which will support the item firmly on the soft flooring material. Rigid plastic shims can also help prevent compression marks on soft flooring materials.

When To Use a BigGap Wedge

Standard Wobble Wedge leveling shims can be stacked and combined using the patented interlocking ridges to fill any gap between furniture and appliances and your flooring material. However, there are some gaps that require a more industrial solution. In these instances, use a BigGap™ Wobble Wedge, which is twice as thick as the standard wedges. BigGap™ leveling wedges can also be stacked and combined to increase height. BigGap™ shims are ideal for large furniture or appliances such as workbenches, storage shelves, hot water heaters, washing machines, and more.

Shim & Stabilize A Hot Water Heater

Whether you’re a professional plumber or capable DIYer, installing a hot water heater takes patience and craftsmanship. Most hot water heaters are installed in basements, garages, kitchens, and restaurants with intentionally unlevel flooring. Concrete floors are designed to slope toward a drain to prevent flooding in your building. However, leaning hot water heaters can be a safety concern and do long-term damage to your property. 

For your hot water heater to work correctly, you don’t want it rocking, leaning, or wobbling. This could stress the plumbing joints and ultimately cause a leak. With just one gallon of water weighing eight pounds, it’s easy to see why these appliances need to be stabilized. First, use a carpenter’s level to check the sides of the hot water heater and ensure it’s straight. When it’s not, Wobble Wedge® plastic shims can ensure your hot water heater works properly and help you avoid costly repairs long term.  

Accommodate for Unlevel Flooring

No matter what type of building, floors are rarely perfectly level. Use Wobble Wedges® to solve unlevel flooring below your hot water heater tank and ease needless stress on plumbing and joints. You can stack and combine Wobble Wedges to get the perfect height. Use as many as necessary. In addition, Wobble Wedge interlocking ridges won’t slip apart once underweight. Wobble Wedge plastic shims are a highly versatile tool with superior functionality that helps you get the job done faster.

Plastic Shims Not Susceptible to Water Damage

Materials like wood or composite are easily penetrated by water and not only warp over time but can affect the stability of your structure. In addition, plumbing issues with hot water heaters can lead to mold and mildew, which can become costly problems. Durable Wobble Wedge plastic shims are not susceptible to water damage. They will not swell or rot, like wooden shims, when placed under a hot water heater tank and exposed to excess moisture or flooding.

Wobble Wedge Holds Up to 2,000 Pounds

Whether you own an under-the-sink, tank, or tankless, also known as on demand hot water heater, we have you covered. Be assured the reliable Wobble Wedges can hold up to 2,000 pounds of weight. That is enough to stabilize and support any hot water heater tank at total capacity. So depending on the type of hot water heater you have, from a 6-gallon tank that weighs 76 pounds up to a 115-gallon tank that weighs 1,183 pounds, there is no job the Wobble Wedge can’t support. 

Tough And Durable For Any Job

Made proudly in the United States, the patented Wobble Wedge comes in all shapes, sizes, materials, colors, and numerous customizable options that make it perfect for any job. Going strong since 1985, we’ve been helping professionals and business owners ensure their projects are done right and on time.

Wobble Wedge®: The History of Plastic Shims

Plastic shim

What Led Us to the First Patented Plastic Shim with Interlocking Ridges

The history of shims starts long before plastic was around. In fact shims or wedges are some of the oldest technology that humans developed. Early shims were made from stone, wood, antlers, and various other natural materials. But modern times call for modern materials, and we needed a solution that didn’t deteriorate or slide around when stacked. So we developed the Wobble Wedge® plastic shim with interlocking ridges. And now over 30 years after it was first created, our plastic shim is still the leader in shim technology.

When Did Humans Develop the Shim?

Shims or wedges are considered one of the six “simple machines” developed by early humans. This list includes the lever, wheel and axle, pulley, screw, and inclined plane. Shims have been around since the stone age, and even pre-date the invention of the wheel. Bronze wedges were used in quarries in Ancient Egypt circa 3,000BC to break and shape rock during mining. There is also evidence that Native Americans used antler wedges to build canoes and dwellings. They also used stone wedges to make tools such as axes and knives (both of which are types of wedges themselves). 

Why Shim Technology Needed New Ideas

With thousands of years of development, interestingly wedges have mostly stayed the same. The most common types of shims are smooth and made of metal or wood. These have their advantages and disadvantages. Metals can be very strong, taking a lot of force, but they can also rust, degrade, and stain other materials when in contact with water. Metal is also quite expensive, and not easily manipulated. Wooden shims on the other hand are cheap, and easily manipulated and shaped. But wood can also warp, rot, and stain other materials when water is present. Both of these options work in certain situations, but they have limitations.

Plastic Shims with interlocking ridges

A New, Modern Shim for Stability

Living in a 115 year old home that didn’t have a level floor board in it, meant all of our furniture wobbled and listed. We decided that we needed a solution that offered stability. Stacking metal, wood, or plastic shims that were available at the time always resulted in the shims slipping and not staying in place. Shims needed some way to grip that would allow them to stack safely and remain firmly where you needed them. This is why we decided to invent the Wobble Wedge®.

The First Patented Plastic Shim with Interlocking Ridges

Wobble Wedges® were invented in 1985 to create a truly modern plastic shim that could eliminate the issues of other shims that were in the market at the time. We designed Wobble Wedges® as an interlocking modular system of tapered shims. The interlocking ridges allowed Wobble Wedge® plastic shims to stack on top of each other. Each plastic shim was designed to resist movement from all directions, no sliding side to side or forward and back. This allowed the Wobble Wedge® plastic shim to stay where you put it, be that gripping a surface or gripping another Wobble Wedge®. We didn’t set out to get patents, but ultimately our designs earned 2 patents for our interlocking ridges. 

Wobble Wedge®, the Most Versatile Modern Plastic Shim

Wobble Wedges® are made from plastic because it won’t rot, warp or cause discoloration when in contact with water. It’s also cheap, durable, and allows us to make plastic shims in both hard/rigid and soft/flexible options. Our hard/rigid plastic shims can take +2,000lbs of force, while the soft/flexible versions are strong and cushioned enough to use with delicate porcelain. We also designed the Wobble Wedge® plastic shim in 4 sizes with the same interlocking ridges so that you can use all 4 sizes together. Wobble Wedges® are equally effective at stabilizing a wobbly restaurant table, installing a toilet or leveling a backyard fountain as they are in shimming aluminium aircraft panels on an industrial assembly line.

Kitchen Projects

There are lots of ways to use Wobble Wedges® in the kitchen, from leveling heavy appliances to tilting your dish rack.

You can also use our plastic shims when installing and leveling a new countertop in your kitchen. 

Bathroom Projects

Wobble Wedge® toilet shims are ideal for bathroom projects because they are unaffected by water.

Yard Projects

Outdoor projects need to withstand all kinds of weather. Our plastic tapered shims won’t rot, and won’t deteriorate out in the elements.

Wobble Wedges® are ideal for work with precast concrete, like building a precast concrete wall or putting in a precast concrete walkway. They can also be used while installing a concrete fountain, a great way to add the beautiful sounds of running water to your garden. Wobble Wedges® can help with installing deck stairs; and if you need to run electrical cords outside they can help keep the cords hidden and prevent tripping.

The Best Plastic Shims for Plumbers

The Best Plastic Shims for Plumbers

Made from Durable Plastic, Wobble Wedges® are Perfect for Plumbers

When we designed Wobble Wedges® we had plumbers in mind! Our plastic shims are ideal for use in bathrooms and wet-rooms, as they won’t warp or deteriorate or cause discoloration if they come into contact with water. Our soft plastic shims are strong enough to provide stability, while also soft enough to be used with porcelain to prevent cracking. Read on to learn why Wobble Wedges® are the best plastic shims for plumbers.

The Perfect Toilet Shim

Whether you’re fixing a wobbly toilet or installing a brand new toilet, Wobble Wedge® toilet shims are perfect for this job. Made of a soft, durable plastic they are firm enough to level a toilet, while providing cushion to the porcelain, preventing cracks. Other methods of shimming (pennies, wooden shims, hard plastic shims, etc.) have their downsides. For instance, being too firm and potentially cracking the delicate porcelain. While wooden shims can rot from water damage. Soft plastic Wobble Wedge® toilet shims won’t have these issues, they are unaffected to water and flexible enough to not cause cracks. Just a few of the reasons why we think Wobble Wedges® are the best plastic shims for plumbers.

To read about using Wobble Wedge® toilet shims to install a new toilet read our blog “How to Install a New Toilet.” And to read about using our toilet shims to fix a wobbly toilet check out our blog “How to Fix a Wobbly Toilet.”

Plastic Shims for Plumbers, ideal for installing toilets

Ideal for Bathtub Installation

While installing a porcelain bathtub you often have to shim it to bring it to level and facilitate good drainage. Just like with toilets, porcelain bathtubs can crack if they are shimmed with a hard, rigid wedge. This is why we suggest Wobble Wedge® soft plastic shims for all projects that involve porcelain. Read more on our blog post “Installing a Bathtub” to learn how to use Wobble Wedges® for this task.

Great for Shower Enclosure Installation

As we’ve mentioned before, Wobble Wedge® plastic shims are ideal for bathroom projects. The plastic won’t warp or deteriorate and won’t cause discoloration from water. This is why they’re perfect for bathrooms and wet-rooms. We believe that our shims offer the stability and durability that plumbers are looking for in a plastic shim. There are several points while installing a shower enclosure that you might have to use shims. Read our blog “How to Install a Shower Enclosure” to see how Wobble Wedge® plastic shims can be used during installation.

Level Bathroom Vanities

If you’re installing a bathroom vanity, Wobble Wedges® can come in handy for this task too. They come in three sizes, BigGaps™ that are .48” high, Standards at .25” high, and Minis at .16” high. With all of these sizes they can be used for many different bathroom tasks. They can also be conveniently stacked, and will stay put, thanks to their patented interlocking ridges. Use Wobble Wedges® to level a bathroom vanity, as well as shim the back of it. Read more on our blog post “Leveling a Bathroom Vanity.”

Plastic Shims for Plumbers

Stabilize Washing Machines

If you’re fixing a washing machine and notice that it’s unbalanced, our shims can help! If the feet on the machine aren’t adjustable, or are stripped, Wobble Wedge® plastic shims allow you to stabilize the machine. Obviously this isn’t a permanent fix. But if your client doesn’t want to pay for you to remove the foot or replace the machine, a hard plastic Wobble Wedge® will fix the problem. To learn more about using Wobble Wedges® to level washing machines, check out our blog “How to Level a Washing Machine.”

Our shims come in two types, hard and soft plastic. Hard shims are ideal for heavy objects, taking +2,000 lbs of force. Both types of shims can be combined, because the interlocking ridges will stay together when stacked. Learn how hard and soft plastic Wobble Wedges® can work together on our blog “Hard & Soft Plastic Shims Work Together.” This versatility means they are the ideal plastic shim for plumbers.

Stop Rattling Pipes

If you’re looking for a quick fix for rattling pipes, our soft plastic Wobble Wedges® come in handy! Because they are made from a flexible plastic, they can bend around a pipe going through a joist to cushion it, stopping the rattle. They can also be used to pad pipe hangers or appliance lines if they vibrate and make noise. Learn more on our blog “Silence Rattling Pipes.”

Wobble Wedges® for Gym Owners and Managers

Stabilize Gym Equipment, Free-standing Weight Racks and More! 

Gym equipment gets a lot of rough use, and can quickly become unstable. This can be a serious safety hazard and liability to your gym. Wobble Wedges® provide the perfect solution to this heavy use, as they are made from a strong, durable plastic. They can easily be carried around in a pocket by gym staff to fix issues as they arise. From leveling heavy gym machines to free-weight stands to locker room issues. Read on for 6 ways gym owners and managers can use Wobble Wedges® throughout their gyms.

Leveling Heavy Gym Machines

Heavy gym equipment needs to be stable and not move around so that your patrons remain safe. If your weight machines rock back and forth, Wobble Wedge® plastic shims can stabilize them. Our hard plastic shims can take +2,000 lbs of force, meaning even your heaviest gym equipment can be stabilized with Wobble Wedges®.

Figuring out where the wobble is might take two people, one to use the equipment and one to look for the imbalance. Once you’ve found where the equipment lifts off the ground, place a hard plastic Wobble Wedge® shim into the opening. If it still rocks, you can safely stack Wobble Wedge® plastic shims because of the patented interlocking ridges. The ridges mean that the shims will stay together and not slip!

Stabilize Treadmills and Ellipticals

Treadmills and ellipticals are definitely some of the hardest working equipment at your gym. The heavy use inevitably means they breakdown over time. To keep your gym patrons safe keeping them level and secure is important. Wobble Wedge® plastic shims can be used to stabilize the feet of these machines if they have stopped being secure. Use the same method as above to find the source of the imbalance. Then use hard Wobble Wedge® plastic shims to bring the machines back to stability.

Leveling Weight Stands

Free weight stands carry quite a heavy load, and if they rock or lean this can lead to weights falling and potential injuries to patrons. To level your weight stands, remove all of the weights from the stand and check it with a level. Place Wobble Wedge® hard plastic shims under the feet that don’t completely make contact with the floor. Replace the weights and check with a level, making sure the unit is stable. Add more plastic shims as necessary.

Leveling Heavy Gym Machines

Stabilize Upright, Horizontal and Wall-mounted Barbell Holders

Barbells can be stored in a variety of configurations, but as they are heavy without adding weights, they need to be secure to prevent injury. Free-standing upright and horizontal holders likely don’t have adjustable feet, so they will need shims to stabilize them. Place a level on the stand and check it in all directions. Insert hard plastic Wobble Wedge® shims under the side of the stand that is opposite to the bubble on your level. Add shims as necessary to bring the bubble to the middle of the level. For wall-mounted holders you would only have an issue if the walls of your gym aren’t plumb. If that’s the case, you will want to use a level when installing your wall-mounted unit. Place plastic shims as necessary under the piece that mounts to the wall. The weight of the holder will keep the shims in place.

Stabilize and Level Free-standing Lockers in Locker Rooms

If your gym has free-standing lockers they can over time become unstable and list. It’s probably no easy task to take apart these heavy units to re-tighten all the screws and joints. So to stop them from leaning, you use Wobble Wedges® to bring them back to level. Place both hands on the locker and gently push it to see where it lifts off the ground. Have a coworker place a hard plastic shim under the corner(s) that lift off. You can use a large level to verify that it’s plumb, but more than likely just stopping it from rocking will stabilize the unit.

Fix Issues in Your Gym’s Bathrooms

Wobble Wedges® are ideal for bathroom projects. Because they are made of durable plastic they won’t rot or warp when in contact with water. They were originally made as toilet shims, as the soft plastic version protects the delicate porcelain and is strong enough to stabilize the toilet. From fixing a wobbling toilet, installing a new toilet, to leveling bathroom vanities during installation, Wobble Wedges® will come in handy! Check out our blog on how to use Wobble Wedges® in bathrooms.

How to Install a Shower Enclosure

How to install a shower enclosure

Plastic Shims Are Perfect For Use in Bathrooms

Installing a shower enclosure is a great way to update your bathroom and improve the value of your home. While installing you will need to use shims to make sure that the unit is level. We highly recommend using Wobble Wedge® plastic shims because they are water resistant. They won’t rot or breakdown over time, making them ideal for use in bathrooms. Here’s how to install a shower enclosure with Wobble Wedge® plastic shims:

How to Install a Shower Enclosure

These instructions assume you have removed your old shower/tub, have chosen the correct size insert for your space, and have an empty opening ready for installing the new shower. Please note that you should always follow the manufacturer’s instructions that came with the shower enclosure. 

  • Verify the level of the subfloor and walls. It is particularly important that the floor is level so that the shower will drain properly. Ripping out the subfloor and installing new so that it’s level is a good idea if it’s very uneven. Wobble Wedge® hard plastic shims can be used to correct any variations in the subflooring by placing them on the studs under the subflooring. When screwing down the subfloor, be sure to place screws in the same locations as the plastic shims to keep them in place. If it’s close to level, you can do some additional leveling during the shower pan installation.
  • Rough in the drain line and plumbing for the showerhead and control valve on one side of the shower wall.
  • Now it’s time to dry fit! Place the shower base into position and check for level on all sides. Add Wobble Wedge® soft plastic shims as necessary to bring it up to level. Tape the plastic shims into place. It is also recommended to place a piece of cardboard in the shower base to protect the finish while you work.
  • Once the base is level, mark the top edge of the base with a pencil on the studs along all three sides of the alcove. Now we’ll dry fit the walls. Start with the back wall of the shower, gently place it in position, locking the bottom tabs into the base. Hold it in place with tape so you can position the side walls.
  • Lock the side wall in place (the one without the plumbing fixtures). To fit the third wall you will first need to cut the holes for the plumbing fixtures. Measure the distance from the edge of the back wall panel to the center of the valve, now measure from the center of the value to the top of the shower base panel. Transfer these measurements to your third wall panel. 
  • Place the third panel on a flat surface to cut out the holes. You will want to use a hole saw for this, and make sure that the size of hole you are cutting is smaller than the cover plate for the fixtures. Drilling from the finished side will give you a cleaner cut. Once you’ve cut the holes, dry fit the third wall in place.
  • Verify the level of the walls of the shower enclosure. If they aren’t level, place soft plastic Wobble Wedge® shims behind the panels along the studs to bring it to level. Tape the plastic shims in place (you will nail them into place later). You can trim the plastic shims with snips or a knife to the right size if needed. Once it’s level, mark the top of the flange (the top of the wall where the nails will hold the walls to the studs) on all the studs around the walls. Carefully remove the walls and shower base.
  • If there are low spots on the subfloor, you can place gypsum plaster or bricklayer’s mortar on the low spots of the subfloor. Now place the shower base back into the alcove, remove the cardboard. Recheck it for level, adding any additional plastic shims as necessary. Make sure it’s correctly positioned over the drain. Using silicone caulk, apply a bead to the space between the shower pan and the drain and around the lip of the underside of the drain flange. Screw the flange into the drain and install the strainer into the drain, tightening both in place.
  • Now we’ll secure the shower base into place. Pre-drill holes around the flange and into every stud. Use roofing nails to attach the shower base to the studs. Place the cardboard back into the base to protect it while you finish installation.
  • Now place the back wall into place, locking it into the shower base. Pre-drill holes through the flange along every stud at the top and down the vertical side flanges, 8 inches on center for the sides. Secure the wall to the studs with galvanized roofing nails. Be sure that the nails go through your Wobble Wedge® plastic shims that you’ve placed along the studs, this will secure them in place. Repeat these steps with the side wall without plumbing fixtures.
  • Fit the third wall in place, verifying that all plumbing fixtures line-up properly. Repeat the pre-drilling and nailing as in the previous step.
  • Now to sealing, one of the most important steps to prevent leaks and moisture issues. Consult the manufacturer’s instructions for sealing the unit. Some enclosures will require caulking, some will not. 
  • You’re almost done! Install water-resistant green board on the rest of the walls in the bathroom. It should overlap the flange on all sides, but leave a ⅛ inch gap to allow for caulk. Prime and paint the walls, and caulk the gaps between the drywall and the flange. Now install the fixtures and trim pieces per the manufacturer’s instructions.
  • Congrats! You can now install a shower enclosure!

PLEASE NOTE: Follow any manufacturer instructions that come with your shower enclosure kit.
