Composite Shims (24 Pack) - Heavy Duty Hard Composite Shims for Leveling - Never Rot Equipment, Machinery, Table Wedges - Stock Your Home

Works well under bathroom slats helps keep slats off of shower floor.

I love these because they will not rot like the cheap wood ones. I am using them in an outside in the elements situation and they work great. The thickness is perfect to give a good step up in thickness when combined or stacked together. Only complaint is cutting them does take a bit of effort but you want them strong, can't have both.

Love these shims I use them outdoors for everything that kind of seems off-balance on my patio and things in my home. They’re perfect because they are just in size and you can break them then to the size you want.

I use them all the time at my workshop. I don’t use them for anything heavy.

Great product. Great value. Very easy to use and it offers lot of flexibility. Happy i decided to use this to fill a gap that had formed between my house and the front steps.

Excellent outdoor and indoor product. Tougher than wood shims. Better for tight or odd jobs. Great for leveling sheds, pool water heaters and filters on concrete slabs. Resistant to water, snow, and weed eaters. Size and length make them best for heavy objects.

Nice product

Used to level in wall Air Conditioner. Easy to use! Consistent and well designed- not going to move! Highly recommend.

Spot on. Long, with gradient very gradually increasing. Three of them have levelled up a garden water feature quite nicely! Highly recommend.
