Butterfly Sink Clips for one Undermount Sink, AL6-08

These butterfly-style undermount sink mounting clips are a preferred choice for granite fabricators installing bathroom sinks beneath granite, quartz, and other stone countertops using a notched cutout mounting method. In this installation style, a small notch is formed in the underside of the countertop adjacent to the sink rim, allowing the clip to seat into the cutout while the fastener tightens the metal tab firmly against the sink edge. This creates a secure mechanical hold that helps installers achieve a clean, controlled fit and maintain proper sink alignment during installation and long-term use.

Designed as dependable undermount sink mounting hardware for stone countertops, this system gives fabricators and installers a straightforward way to secure most standard ceramic undermount bathroom sinks without relying on adhesive on the hardware itself. A bead of silicone around the sink rim is still required to create a proper seal and help prevent moisture intrusion, but the clip system itself provides the mechanical support. This makes it a practical solution for professionals looking for reliable undermount sink support for granite and quartz installations.

Each installation set includes four butterfly clips, four wing nuts, and four screws, providing the hardware needed to mount one undermount bathroom sink using the notched support method. The adjustable design allows the clips to tighten evenly against the sink and countertop surface, helping maintain alignment and consistent pressure during installation.

Ideal for new installations or replacement undermount sink mounting hardware, this clip kit is intended for most standard ceramic undermount bathroom sinks designed for notched clip installation. Preferred by granite fabricators for its clean application and secure hold, it offers a professional sink mounting solution that helps reduce shifting over time and supports long-term performance.
