These butterfly-style undermount sink clips are engineered for installation methods that use a notched, or “butterfly,” cutout beneath the countertop. This mounting style provides solid mechanical support without requiring silicone or adhesive on the hardware itself, giving installers a cleaner, more streamlined setup. A silicone bead around the sink rim is still necessary to create a watertight seal and prevent moisture issues.
This bulk case contains 100 complete installation sets, ideal for contractors, multifamily developers, and project managers who need reliable hardware stocked for large-scale bathroom installations. Each individual set includes four butterfly clips, four wing nuts, and four screws—everything required to mount one ceramic undermount sink using a notched-cutout support method.
Designed for consistency and dependable performance, these bulk installation sets deliver a sturdy, well-balanced hold that keeps undermount sinks securely positioned over time. With hardware sized for standard ceramic models and a simple, adjustable fastening design, they offer a practical, ready-to-use solution across varied job sites and project demands.
