Snap-On Collars

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.

Vent & Shutter Covers

Vent & Shutter Covers
Vent and shutter covers attach to the exposed face of an HVAC vent and block airflow into that space. This allows users to control airflow through vents that do not have dampers or other airflow control methods. They are made of flexible, magnetic strips that attach to magnetic metals and are easily installed and removed.
