Collars

Wide selection of galvanized duct collars, including spin-in collars, fishlock collars, and C-Vent storm collars.

Secure Duct Transitions and Connections

Made from galvanized steel, these collars—such as spin-in, fishlock, and storm collars—create a secure, airtight seal for efficient airflow and reduced leakage. Whether used for round or rectangular duct applications, HVAC collars provide a stable mounting point for attaching flexible or rigid ducts, making them a critical fitting for both residential and commercial ductwork installations.
