Description
Rotaire 3920 – 2″ heat outlet vent
The 3920 Rotaire Vent is the new contemporary redesign of the classic 3820 Rotaire. The two-piece, snap-together design covers all screw heads and offers a clean updated look. The base section and screw-hole placement is identical to the 3840 and no alterations are necessary to exchange the two parts.
All the features found in the Rotaire Vents are found here in D&W’s 3820 reducing outlets. These reducing outlets retain the wide mounting flange while accepting 2″ diameter duct hose.
