The #3940 Rotaire Vent is the new contemporary redesign of the classic 3840 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.

The Rotaire line offers the ideal properties for increased efficiency in all heating and air conditioning applications: 360 rotation, easy installation and long term durability. The Rotaire Grille has an over-all diameter of 5-1/2″ and is designed for accepting all types of 4″ Flex Duct. Available in Dura-Beige, Walnut, Black, and White.
