Deslauriers Key Slot Shims are engineered plastic shims designed for quick, precise leveling and alignment around anchor bolts, key slots and other construction connection points. Their slotted design allows the shim to be installed without removing the anchor or component being supported.
Deslauriers describes Key Slot Shims as an economical solution for leveling and alignment in demanding construction environments. The engineered plastic provides excellent compressive strength and load-bearing surface contact while resisting moisture, alkalis, ground chemicals and microorganisms.
Key slot shims are shaped to snap into place around a 7/16” bolt with a restricted slot to keep them from sliding off a bolt or anchor when hung vertically.
