Description
Professional-Grade Sink Mounting Without Drilling
The ChemSet Undermount Sink Clips provide a secure, non-intrusive solution for mounting undermount sinks—no drilling required. Designed for countertop fabricators, installers, and contractors, these clips offer fast, damage-free installation on natural stone, quartz, and solid surface countertops.
Unlike traditional mechanical fasteners that require direct drilling (which can weaken countertops and lead to cracks), ChemSet Undermount Sink Clips use an industrial-strength adhesive bond for a secure, long-lasting hold.
