Nelson Pre-Scored Composite Shims, 8", 32 Per Box

Nelson Pre-Scored Composite Shims provide dependable leveling and support for countertops, cabinets, sinks and stone installations. Manufactured by a trusted shim producer with more than 50 years of experience, these waterproof composite shims support 35% more load than traditional wood shims and snap up to four times more easily.

The thin, pre-scored profile allows each shim to be snapped to the required length without sawing. This produces clean, consistent breaks while reducing installation time, unnecessary waste and rough or splintered edges.

Unlike traditional wood shims, the composite material resists moisture, insects, splitting and splintering. It will not rot, sag, swell or warp, making these shims suitable for permanent placement near sinks, dishwashers and other moisture-prone areas.
