Composite Shims and Leveling Wedges (12 Pack, 8") - Made in USA - Extreme Load Support Plastic Shims for Leveling - Table, Floor, Doors, Toilet, and Furniture Levelers

If u have a plastic shed that’s uneven and problems with doors get these shims perfect for the job good quality great buy

Purchased these to level a Raised Wildlife Barrel Pond on my patio. They did the job perfectly, although I had to use several to get the level I wanted (patios of course do tilt away from the house). However, pond is now perfectly level. As these were so useful, I will purchase some more for any future use.

Strong

I bought these when putting together a plastic shed. I'd built a base but needed these to get the shed perfectly level. They work a treat.

Useful addition to my DIY kit that has enabled me to undertake minor repairs around the house

Perfect for levelling my Pax wardrobe, good quality and a good size

Did the jobs perfectly, very easy to use and snap to size

Used these for my Keter Shed, now the door shuts fine and the entire shed is straight. Easy to use and don't hesitate to use more than one in the same place.

Good shims, strong but flexible and easy to work with

Excellent shims for projects exposed to the elements, like decks. I found that a sharp chisel cuts them in place better than a knife.

Looks to be of high quality!!

These are very useful when you are working on old homes where nothing is straight.

It says they're stackable but I haven't been able to figure out how to stack them so they stay put. They kind of fit together, but they don't lock together at all. I need to stack 4 of them under my bird bath, which I empty and clean pretty regularly, and I have to keep redoing it. Not a huge deal, but I was expecting more.
