Slotted Shims

The slot lets you insert, remove, and adjust the shims without disassembling your machinery, while the tab keeps fingers and tools away from machine feet. Use an insertion tool (sold separately) for better leverage and reach. Shims are etched with the thickness.
18-8 stainless steel shims have a balance of strength and corrosion resistance.

Large-Adjustment Slotted Shims

Use these thick shims to align cabinets, doors, and windows, or for other rough leveling. They're color-coded by thickness for easy identification. The slot makes it easy to insert, remove, and adjust the shims. Shims are made of plastic to resist moisture and prevent rot.
