Nelson Composite Shims are engineered for professional and DIY installations where moisture, durability and ease of use matter. These shims solve the common problems of wood shims: they won’t rot, split, or attract insects, making them ideal for exterior doors, windows, framing adjustments and any project exposed to moisture or humidity. The composite material delivers greater load-bearing capacity than traditional wood shims while remaining simple to snap and position.
At 8 inches long and 1-1/2 inches wide, each shim is tapered from 5/16 inch down to 1/32 inch. The design enables quick, clean breaks for faster installations. Each shim fits easily into a tool belt for convenient access on site.
