NSI Solutions Twist Shim and Driver

Level granite, quartz, and stone countertops faster with the innovative Twist Shim installation system.

Looking for a Faster Way to Level Countertops During Installation?

The NSI Solutions Twist Shim and Driver System is designed to simplify countertop leveling while dramatically reducing installation time. The specially engineered Twist Shim Driver attaches to most drills or wrenches, allowing installers to quickly position and adjust Twist Shims from underneath the countertop without repeatedly lifting heavy stone slabs.

Twist Shims are purpose-built for granite, quartz, and other stone countertop installations. Once installed through a 5/8" hole, they allow precise height adjustments by simply rotating the shim from below. After the countertop has been perfectly leveled, adhesive can be injected directly through the center of the shim to permanently secure the installation.

This innovative system helps installers complete jobs more efficiently while reducing physical strain and minimizing the risk of damaging expensive countertop materials.

For complete countertop installation solutions, pair the Twist Shim System with our countertop installation accessories and professional stone adhesives.

Why Choose NSI Solutions Twist Shim and Driver?

Traditional countertop leveling often requires repeatedly lifting and repositioning heavy stone slabs while inserting standard shims. The Twist Shim System eliminates much of this labor by allowing precise adjustments from underneath after the countertop has already been positioned.

Once the desired height has been achieved, installers can inject adhesive directly through the center of the shim without disturbing the countertop. This unique design speeds installation, reduces physical strain, and helps produce more accurate countertop leveling.

Whether you're installing granite, quartz, or engineered stone countertops, the NSI Solutions Twist Shim and Driver System provides a faster, cleaner, and more professional installation process.
