16-Piece Zinc Alloy Cable Connectors

This set supplies sixteen clamp-type connectors sized for a standard 1/2 inch electrical box punch-out. They are intended for electricians and installers who need to secure metallic conduit and protect cables in residential or light-commercial wiring jobs. The UL listing confirms compliance with recognised safety requirements.

Sustained Installation Reliability

The zinc alloy construction resists rust and deformation when the connectors remain in place for extended periods. Each clamp maintains its grip on conduit without loosening under vibration or thermal cycling typical of permanent wiring runs. The pack quantity supports multiple circuit pulls without running short mid-project.

Build Quality and Daily Fit

Made from zinc alloy, the bodies withstand repeated tightening and job-site handling without stripping or cracking. The 1/2 inch clamp matches standard knock-out dimensions, so no special tools or adapters are required during box preparation. Installers simply open the punch hole and screw the connector onto the cable for a secure mechanical bond. Not suited for non-metallic sheathing or oversized conduit that exceeds the 1/2 inch clamp capacity.
