These butterfly-style installation clips are designed specifically for undermount bathroom sinks that use a notched or “butterfly” cutout beneath the countertop. This system creates a secure mechanical hold without requiring any silicone or adhesive directly on the hardware, allowing installers to achieve a cleaner, more controlled fit. A bead of silicone around the sink rim is still required to form a proper seal and prevent moisture intrusion.
This single installation set includes four butterfly clips, four wing nuts, and four screws, everything needed to mount one undermount sink using the notched-cutout method. The adjustable design allows the clips to tighten evenly against the sink and countertop surface, helping maintain proper alignment during installation.
Ideal for replacing missing hardware or completing new installations, these butterfly clips offer a straightforward and reliable way to secure most standard ceramic undermount bathroom sinks using the notch-support system. They provide a stable, professional hold that supports long-term performance and reduces the chance of shifting over time.
