These 100 bulk sets of butterfly-style undermount sink clips are a preferred choice for granite fabricators, contractors, and project teams installing bathroom sinks beneath granite, quartz, and other stone countertops using a notched or “butterfly” cutout method. This installation style creates a secure mechanical hold at the sink rim, giving installers a clean, controlled mounting solution 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.
Packaged for volume purchasing, this bulk case is designed for multifamily projects, large installation schedules, and shops that want dependable undermount sink mounting hardware on hand while reducing per-set cost. Each case includes 100 complete installation sets, making it a practical option for buyers looking to save in bulk while maintaining consistent hardware across multiple jobs.
Each individual set includes four butterfly clips, four wing nuts, and four screws to mount one ceramic undermount bathroom sink using the notched-cutout support method. The adjustable design allows for even tightening against the sink and countertop surface, helping maintain alignment during installation and supporting a secure long-term hold.
Ideal for fabricators, contractors, and project managers stocking hardware for repeated use, these bulk undermount sink clip sets offer a reliable and economical solution for large-scale bathroom sink installations. Preferred by granite fabricators for their straightforward application and dependable support, they help simplify procurement while delivering consistent installation performance across job sites.
