What Customers Are Saying

Customers overwhelmingly praise these composite shims for outperforming wood alternatives—they don't split, warp, or degrade, making them ideal for doors, windows, cabinets, and subfloors. Reviewers highlight their stackability, precise 1/16" adjustments, smooth insertion, and durability in damp environments. Many appreciate the ease of use and keep multiple packs on hand. Some report inconsistent breaking or snapping, and a few note the flat shape requires stacking rather than gradual adjustment. Overall, most consider them the most reliable shim option available.

Easy to use shims

Would Recommend

Theae worked exactly the way i needed them too. The fact that they are composit is a plus as I don't envision they will rot anytime soon.

Versatile

Would Recommend

Worked with both my new construction windows and new front door install. Could use a groove molded into the design to keep the shims centered on each other.

Easy to use

These are easy to stack and snap off. They are not beveled so you can’t drive them in.

Very good product, wellfold out.Whoever invented i

We use thousands of them to shim roofs, doors and windows. They're not going to ride in there. They're not gonna attract any insects, and they're gonna be goof proof for many, many years.
