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.
