Snap-On Collars
Snap-on collars connect to HVAC diffusers and provide a mounting point for the connected ducts. They are made with two different types of connection, depending on the application. Flange-type collars are compatible with perforated T-bar diffusers. Tab-style units connect with fiberglass-backed diffusers. They are made using rigid metals to provide a secure mounting point between the duct and vent.
