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

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.

Very useful and useable shims. Happy to recommend them.

Strong

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.

Does what it says on the tin. Sturdy plastic used which are easily stackable to get the prefect elevation needed.

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

They are good, shame there’s not a few more for the price.

Useful and snap to length well
