Round Snap-On Collar 12 in 14 in
The round snap-on collar fits a 12 in nominal duct diameter and has a 14 in overall diameter. It is made from galvanized steel at 18 ga thickness with a snap lock coupling. The component is designed for use with perforated T-bar diffusers and includes a nylon element.
Limits of Snap Lock Coupling
The snap lock coupling provides a mechanical connection without separate fasteners, but it relies on the duct and diffuser tolerances being within the range the collar accommodates. Ductwork that is out of round or has damaged edges can prevent a secure fit, and the 2 in overall height limits the space available for engagement.
Installation Notes
The collar slides onto the duct and snaps into the compatible diffuser models listed by the supplier. Misalignment during insertion is the most common issue, often causing the lock to seat partially and leak air. The Proposition 65 notice indicates the product contains chemicals known to the State of California to cause cancer and reproductive harm.

Questions about this item
Should I pick the 12 in or 14 in version for my duct run?
The collar fits a nominal 12 in duct and has a 14 in overall diameter, so choose it when your ductwork is sized to 12 in.
What does the 18 ga thickness mean once the collar is installed?
At 18 ga the galvanized steel provides rigid snap-lock coupling strength while staying light enough for standard T-bar diffuser mounting.
How does the snap-lock coupling limit the installation?
The snap-lock end only mates with compatible perforated T-bar diffusers such as Grainger 4JRL3, 4MJU5 and 4MJV5, so it cannot be used with other diffuser types.
