Southwark Metal 121SC10 Snaplock Collar 10 Inches

Product Description

The SOUTHWARK METAL 121SC10 is a 10-inch snaplock collar used to connect round duct sections in forced-air HVAC systems. The snaplock design allows the collar to be assembled and locked into position without tools, reducing installation time on residential and light commercial ductwork runs. HVAC sheet metal installers and duct fabricators use this collar to create secure, low-leakage connections at duct takeoffs, transitions, and branch points throughout a duct system.

This snaplock collar is suited for residential and light commercial forced-air applications where a 10-inch round duct connection is required. It fits into standard trunk-to-branch connections, plenum takeoffs, and inline duct fittings. The collar is designed for use with standard 10-inch round spiral or snap-lock duct and is a common component in new construction and retrofit ductwork installations.
