Breakaway Shim Plates
These thick shims are scored to make size adjustments easy—break off the excess shim for a custom fit around fasteners or corners. Unlike wood shims, these plastic shims resist moisture and won’t rot. Use them to align cabinets, doors, and windows, or for other rough leveling.

Slip-Resistant Shim Plates
The textured surface of these thick shims keeps them from sliding apart when stacked. Use them to align cabinets, doors, and windows, or for other rough leveling. They're color-coded by thickness for easy identification. Unlike wood shims, these plastic shims resist moisture and won’t rot.
