Fall Exterior Uses for Wobble Wedges®

Fall weather is officially here and we’re thinking about all of the wonderful ways that Wobble Wedges can be useful inside and outside of the house. Wobble Wedge plastic shims are available in three sizes to solve all of your wobbles and three colors to blend into your environment. These useful plastic shims won’t rot or expand when exposed to the outside elements, making them perfect for exterior residential and maintenance applications. Get started with a variety pack of Wobble Wedges as you set out to accomplish everything on your fall exterior to-do list.

Small Plastic Shims for Stabilizing Decorative Pumpkins and Gourds

Nothing says fall like a motif of pumpkins and other gourds on the steps leading up to your entryway, but pumpkins never have even bottoms, making precarious work out of assembling a perfectly aesthetic arrangement. Use Wobble Wedge Mini plastic shims or clear flexible Wobble Wedge standard size shims to place pumpkins and gourds with perfect precision. Use Wobble Wedges patented interlocking ridges to stack and combine shims to fill any compensate for even the most asymmetrical of pumpkins. Your front porch fall ensemble will look ready for the cover of a magazine and certainly ready for Trick or Treaters to come trotting up the walkway.

Use Wobble Wedges to Hold Exterior Mats in Place

Do your exterior entryway mats slide when it rains or snows? Wobble Wedge plastic shims possess a small hole in the top that allow them to be screwed down to surfaces with a standard size screw. Use two or more Wobble Wedges to batton the edges of your mat down to your porch to prevent any future slipping or sliding of the mat. This technique also works for holding down the edges of exterior decorative carpets and rugs. Keep the edges of an outdoor rug from curling up by tacking them down with color-matched Wobble Wedges available in white, black, and clear plastic.

Level Storage Shelves in Garages, Basements, and Tool Sheds

Storage shelves can get loaded with hundreds of pounds of gear, tools, and storage items. Don’t let your precious items rock on a precarious shelf. Ensure large and heavy storage shelves are perfectly level, prior to loading them with items, using Wobble Wedge plastic shims. BigGap Wobble Wedges offer a solution for large gaps caused by sloped or uneven concrete garage or basement floors. Use the interlocking ridges to stack and combine Wobble Wedges until storage shelves are perfectly level and able to bare weight. Once the shelves are loaded and bearing weight again, Wobble Wedges will not slip or slide out of place.

Level Storage Bins for Stackability

Use Wobble Wedges to level all of your storage bins for the ultimate stackability and security of items. Plastic storage bins can become warped over time or misshapen due to their contents. Make sure that each layer of bins sits level so the next layer can stack on top with Wobble Wedge plastic shims. This is also a good solution when stacking bins of different sizes. Make sure smaller bins sit level on top of larger bins and that each layer can bear the weight of the next without damaging items in the containers.

Mini Wobble Wedges

Wobble Wedges ® have unlimited uses, check out our many blogs to see just some of the many ways they’re useful to have in your toolkit. And our Mini Wobble Wedge ® is no exception! Below we’ve shared just 10 ways to use Mini Wobble Wedges ® to level, shim, shore up and stabilize all kinds of situations in your home.

1. Level Small Wobbles

Mini Wobble Wedges ® are a tapered shim that’s just 0.16” high, which means they are perfect for leveling any small wobble you find in your home. The flexible plastic version can be easily cut to size with scissors or a blade. The rigid plastic Mini is able to take +2,000lbs of force, even though it’s our smallest plastic shim. Mini Wobble Wedges ® also have our patented interlocking ridges that allow them to be safely stacked to whatever height you need. And they can interlock with our other larger wedges too, Standard and BigGap ™.

2. Level Antique Collectibles

Antique collectibles let you have a little bit of history in your home. From antique clocks to figurines, vases to antique lamps, all of them can be a little unsteady after so many years of use. Many antique items were handmade, which can also contribute to their uneven footing. Luckily our soft/flexible plastic Mini Wobble Wedges ® can level all kinds of items. And because of their soft texture they won’t scratch or dent wood, porcelain, or other delicate materials.

3. Secure Objects on Slick Surfaces

If you have something sitting on glass or polished stone, you might want to keep it from sliding around. The patented interlocking ridges on all of our flexible Wobble Wedge ®  plastic shims can gently grip the slick surface under an item to hold it in place. Use several Mini Wobble Wedges ® evenly spaced under the object to lift it and add grip. This will help it stay in place and can prevent marks on the smooth surface too.

4. Fix Loose Antique Furniture Legs

If you have an antique table that’s got a loose leg, you likely don’t want to damage it further by using nails or screws to fix it. So what’s a way to fix the issue without causing more damage? Use our Mini Wobble Wedges ® plastic shims to fix the loose leg, no one will be able to tell and no nails or screws needed. Get the instructions on our blog “How to Fix Loose Legs on Antique Furniture”.

5. Level a Glass Tabletop

If you have a glass table top that doesn’t sit level or that rocks back and forth, you’re probably not sure how to fix it so it still looks good. We recommend using our flexible plastic Mini Wobble Wedges ®. The very translucent and clear plastic will be hard to notice. Additionally the soft plastic shim will cushion the glass and hold it in place while also stopping the wobble.

6. Stabilize Tabletop Decorations

Decorative items on side tables and coffee tables are highly visible, so if they wobble and lean it can be an eyesore. Shimming them with a wad of paper though isn’t going to look good in such a visible location. This is why Mini Wobble Wedges ® plastic shims are perfect to shim these items. Our plastic shims come in a clear plastic that won’t be visible, especially if you trim the shims to size. They will discreetly stabilize all of your tabletop decorations.

7. Prevent Scuffs Marks From Hanging Frames

What do you do when your hanging frames leave scuff marks on your wall? It doesn’t just look bad to have a scuffed wall, if you rent it can mean you’ll get charged for repainting the rooms when you move out. This is a perfect situation to use Mini Wobble Wedge ® plastic shims! The soft/flexible plastic of our shims makes for the ideal buffer between your hanging art and the wall. Read more on our blog “Stop Scuff Marks from Hanging Frames”.

8. Level Houseplants

Don’t let an unsteady houseplant take a tumble from a stray elbow or a curious pet. Most houseplants will survive a fall, but that beautiful pot it was planted in probably won’t! Mini Wobble Wedges ® or our Standard plastic shims can do the trick of stabilizing and leveling plants. Read more in our blog “How to Stop Wobbling Potted Plants”.

9. Level Decorative Ceramic Objects (Bowls, Vases, Sculptures)

Handmade ceramic pieces often have a little wobble from being made by hand. This can mean the special object is less steady, and could be knocked over more easily. Luckily Mini Wobble Wedges ® plastic shims offer a solution, their soft/flexible plastic will delicately hold the ceramic and still keep it level. Cut the plastic shims to the right size to hide them from view.

10. Stabilize Decorative Collections

Lining up decorative collectibles on shelves or in cases is a great way to show off your prized collection. If the items are delicate or unsteady, using a small tapered plastic shim to stabilize them will make it easier to feel safe showing them off. Or if you want to just slightly tilt the items forward to show them off better on a higher shelf, our Wobble Wedges ® are perfect for giving them the best visibility. Simply place a couple of our Mini Wobble Wedges ® or Standard plastic shims underneath the backside of the item and it will gently tilt it into view. This works particularly well for items that are still in their original boxes!

How to Stop Wobbling Potted Plants

Steady Your Houseplants with Wobble Wedge® Plastic Shims 

A beautiful indoor plant jungle can transform a home into your own private oasis. And caring for houseplants is a wonderful way to de-stress and feel connected to nature. If you have a plant that is unsteady or wobbles it can be easily knocked to the floor by a stray elbow or a curious pet. Most houseplants will survive a fall, but that beautiful pot it was planted in probably won’t! So what to do when you have an unsteady houseplant? Here’s how to stop wobbling potted plants with the help of Wobble Wedges®.

Stop Wobbling Potted Plants

There are many types of planters and pots that your houseplants can live in. From ceramic to plastic, some with attached trays and some with separate ones. Luckily if your potted plant rocks back and forth it doesn’t matter which kind of pot it’s in. Our solution will work with them all. You might be tempted to grab a piece of cardboard or a wooden shim, but if these options get wet they can grow mildew or rot. Using a plastic shim to stabilize your potted plant is the best option.

Our Wobble Wedge® plastic shims aren’t affected by water. So they can be used to shim the pot in the water tray or under the tray. Simply take a soft/flexible plastic shim in the color of your choice (black, white, or clear/translucent), and place it under the edge of your pot. The soft plastic will cushion the pot and grip it at the same time, putting a stop to your wobbling potted plant.

Stop Wobbling Potted Plants

How to Level a Plant Stand

If your plants are on wire or wooden plant stands, these too can become unsteady. This is especially common with wire plant stands, where one or more legs is shorter than the rest. Take your plant out of its stand and rock the stand to determine which leg is shorter. Place one or more soft plastic shim under the feet of your plant stand. If you want to make sure it’s level, get a small level to check it front to back and side to side. If it leans to one side you will need to use more than one plastic shim to get it level.

Luckily Wobble Wedge® plastic shims come in three sizes, so you can get the exact height you need. A Mini Wobble Wedge® is 0.16” high, a Standard is 0.25”, and a BigGap™ wedge is 0.48” tall. If you need to combine them to get the perfect height you can safely do this thanks to our patented interlocking ridges. They allow Wobble Wedge® plastic shims to be safely stacked, no slipping! Once you’ve fixed the wobble, return your plant to the stand. Voila, you’ve learned how to stop wobbling potted plants!

Stop Annoying Compression Marks in Carpet

Compression Marks in Carpet

Plastic Shims can help prevent unsightly indentations from furniture

Heavy furniture can leave some serious indentations in carpet! Small feet on furniture put a lot of pressure on the carpet fibers, compressing them under the full weight of the item. But how to stop these annoying compression marks in carpet? Spread out the weight of the furniture over a larger area. This is where Wobble Wedge® hard/rigid plastic shims come in! Read below for info on how to fix the compression marks you already have in your carpet, and how our plastic shims can prevent new ones.

How to Fix Compression Marks in Carpet

If you’ve moved your furniture around in a carpeted room you’ve definitely had to deal with compression marks. These annoying spots where the fibers of your carpet just won’t “bounce back” like they should. There are two common suggestions for fixing a compression mark. Most common is using ice cubes. Place an ice cube (or more than one depending on the size of the indent) in the compressed area. Let it melt, after melting the water should have expanded the compressed fibers. Blot up the excess water and fluff the carpet with your fingers. The second option is to use steam. Take a damp towel and place it over the indentation, use a clothes iron set to medium (with steam) and iron over the towel for about a minute. DO NOT iron the carpet directly, as the iron will melt the carpet! The steam will do much the same thing as the ice, and expand the fibers of the carpet. Then fluff with your fingers. 

Compression Marks in Carpet

How to Use Plastic Shims to Prevent Compression Marks in Carpet

But how do you prevent compression marks in your carpet to begin with? One suggestion is to move each furniture item a few inches every couple of weeks. But that just seems like way too much work to do forever! The better solution is to disperse the weight of the furniture item over a larger area. Narrow legs on furniture put all of the weight down in one tiny spot, compressing the carpet and leaving a mark. A wider foot spreads out the weight over a larger area and doesn’t compress the carpet as much. This is why using a Wobble Wedge® plastic shim under the feet of your furniture can prevent compression marks. Simply take a hard/rigid standard Wobble Wedge® plastic shim and place it under each foot. Our hard/rigid plastic shims come in both clear and black plastic, so they can blend into your decor. And Wobble Wedge® hard/rigid plastic shims can take +2,000 lbs of force, so even your heaviest armoire or display case can easily be supported.

How to Level Countertop Appliances

How to Level Countertop Appliances

And Stop Them From Scooting Across Your Counter

Small countertop appliances can annoyingly wobble every time you open the door or move out of place on slick surfaces. They also typically don’t have adjustable feet like larger appliances. So you might be wondering how to level countertop appliances? Luckily our soft/flexible Wobble Wedge® plastic shims offer a great solution for both of these problems!

How to Level Countertop Appliances

More than likely your countertop appliances don’t have adjustable feet. This makes it hard to stop your countertop appliances from rocking or leaning. Wobble Wedges® offer a sleek solution that will blend in and fix this issue. Take a small level and place it on top of your countertop appliance. You will want to check it for level from two directions, front to back and side to side. On your level the bubble will move to the side that is too high. Place a Wobble Wedge® plastic shim under the foot on the opposite side from the bubble. Check with the level again, repeat by placing a plastic shim under each foot as necessary. Our soft/flexible plastic shims are best for this application. They are sturdy and will provide grip to the surface of your countertop.

Stop Scooting Appliances

Don’t let your countertop appliances slowly creep across your counter! This is likely due to the rubber feet aging, and the rubber becoming hard and brittle. A great solution is to place soft/flexible Wobble Wedge® plastic shims under the feet to improve grip. Our soft/flexible plastic shims are ideal for this use because the patented interlocking ridges grip the slick counter surface. Depending on the size of the feet on your countertop appliance you can use Mini Wobble Wedges® or Standard Wobble Wedges®. Place the plastic shims under the front two feet or all four, depending on your situation.

Don’t Forget to Level Your Big Appliances Too!

It’s also important to level your larger appliances in your home too. You can learn how to level your refrigerator, stove and dishwasher, as well as your washing machine from our blogs. Making sure that your appliances are level is important for safety and for ease of use.

PLEASE NOTE: Wobble Wedges® should not come in contact with hot surfaces. DO NOT place Wobble Wedge® plastic shims against a surface that will become hot when the appliance is in use. Please always consult the appliance manufacturer’s instructions before attempting any adjustments to your appliances.

How to Level a Workbench

Level Your Workbench for Ease of Use and Safety

A lot of workbenches are in garages on concrete slabs. Most garage floors are set up to drain any moisture that might accumulate. Meaning they’re poured so that they slope and aren’t level. Placing your workbench on this surface is bound to cause it to lean. This can be dangerous, as tools roll off and a rocking bench could mean accidental injury too. Luckily Wobble Wedge® plastic shims are strong and durable. Our plastic shims are perfect for leveling heavy objects, taking +2,000lbs of force. Here’s how to level a workbench: 

Why Level Your Workbench?

Workbenches serve a lot of different functions, from tool catch-all when not in use to vital asset during a task executed with precision. When you pile tools on your bench it’s important to have it level so that they don’t roll off. It’s that simple. If your bench wobbles or slopes your expensive hand tools could go clattering to the floor and be damaged. It’s equally important to have your workbench level when you are working at it. Imagine you’re planing a piece of wood and right at the end of your pass the bench rocks and your plane digs in tearing out the wood grain. There are so many instances where a wobbling or moving workbench could be disastrous and downright dangerous! So level your workbench for ease of use and safety.

How to Level a Workbench

Get Out Your Level!

If your workbench has legs and rocks back and forth, push on the corners to determine which of the legs are lifting off the ground. More likely than not, one of the legs that lifts will need to be shimmed. If the workbench has cabinets under it, you might not be able to see which sides are lifting up. In both cases, take at least a one foot level and place it back-to-front and side-to-side on your bench. On your level the side that has the bubble is the higher side of the bench, so you’ll need to shim the opposite corner.

Stabilize with Wobble Wedge® Plastic Shims

Take a hard/rigid Wobble Wedge® plastic shim and place it under the side of the bench that’s too low. Our hard/rigid plastic shims can take +2,000lbs of force, so even your heaviest tool bench should be covered. If the gap is bigger than a single Wobble Wedge® plastic shim, no worries! You can safely stack our plastic shims thanks to their patented interlocking ridges. These ridges keep the plastic shims from moving when stacked. Allowing you to use as many plastic shims as necessary to do the job. After placing your plastic shims, verify that it’s level. Congrats! You’ve learned how to level a workbench!

How to Install Replacement Windows

Plastic Shims Work Great to Hang Replacement Windows

Installing replacement windows can be a great DIY way to improve the insulation and value of your home. These instructions are for situations where the window frames are in good enough condition that you don’t need to strip the window down to the studs. If the frames are in good condition, you can simply install a slightly smaller window into the existing frame, making this an easier DIY than a full frame installation. This article assumes you’ve already removed the old window and prepped the opening. Here’s how to install replacement windows:

Order Your New Windows

You’ll need to measure the opening of your existing frame to determine what size window you should order. Open the window and measure from the lowest point to the top of the frame. Because things move over time, measure it on either side and the middle, measure the width too, top, middle, and bottom. The smallest measurement is the size you should order for your windows, otherwise it might not fit. Order the window ½ to ¾  inches smaller than the opening, this allows enough room for adjustments, caulk, insulation, etc. 

How to Install Replacement Windows

  • Clean the opening: Remove any debris, using a shop vacuum cleaner to remove any dust, or wipe it down with a slightly damp cloth if you don’t have a shop vac.
  • Prep the Sill: Take flashing tape and cut it the length of the window sill. Place it so that it covers the bottom ledge of the interior side of the window, this is important for waterproofing. Carefully place it so that it is fully flush in the corners. Using a level check that the sill is level. If it bows use hard/rigid Wobble Wedge® plastic shims to bring the sill up to level. Once the plastic shims are in place and you’ve verified it’s level, screw each plastic shim in place (you can use the pre-drilled holes in Wobble Wedges®) and use more flashing tape to hold the plastic shims in place.
  • Dry fit the window: there should be a small opening all the way around the window.
  • Caulk it: Using an elastomeric caulk (it will be flexible and expand/contract with the seasons giving you a good seal) apply a ⅜-inch bead all the way around the exposed inner face of the exterior casings. Apply two beads of caulk along the windowsill (bottom).
  • Put the window in place: First put the bottom of the window in position and then tilt the top of the window into place. Press it firmly against the caulk. Hold it in place with hard/rigid Wobble Wedge® plastic shims at all of the pre-drilled frame screw holes. Screw through the pre-drilled holes, and through the shims. Don’t tighten the screws all the way so that you can do the next step.
Hold the window in place with plastic shims.
  • Check the position: Make sure that the sashes sit evenly in the frame. If there are uneven gaps, position a hard/rigid Wobble Wedge® plastic shim at the meeting rails (where the sashes meet when the window is closed) to make the spacing even. Verify that the window is plumb, level and square (be sure to measure diagonally to check for square). Also make sure that the window opens and closes properly. Adjust around the edges of the window with hard/rigid plastic shims. After all measurements are right, score and snap the Wobble Wedge® plastic shims to remove excess. Finish tightening the screws.
  • Fill the gaps: From the outside, gaps around the window that are less than ¼ inch wide can be filled with the same elastomeric caulk used earlier. If the gaps are larger than ¼ inch, prefill them with backer rod weatherstripping, and then caulk. For gaps inside you can use a minimally expanding foam or the elastomeric caulk to fill the gaps.
  • Last steps: Reinstall the stops or add new ones. Finally you’re ready to prime and paint or stain the window sash and frame! You’ve now learned how to install replacement windows! Congrats!
