NSI Twist Shimâ„¢ System

Alternative Views:

NSI Twist Shims™ are a truly revolutionary simple design to make installations and repairs faster and more cost effective. The labor saved by using these shims will more than make up for the cost of the product. Granite counter tops and other stone tops can be adjusted and leveled from underneath, without having to lift the tops up again. Not only that, silicone, epoxy, caulking and other adhesives can be injected directly through the center of the shims to bond the countertops to the subtop.

Sold individually, packs of 50 and packs of 200
