Return Hood: Metalaire
Metalaire has released its Non-Ducted Return Hood. The Model NDRH is intended to be a field added accessory to return grilles in non-ducted plenum applications. The company claims the model significantly reduces the amount of sound transmitted into or from the plenum and also functions as a light shield. It can be used with any of METALAIRE's T-bar lay-in return grilles specifically for use in non-ducted return applications. Constructed is of 22 ga. galvanized steel and lined with ½-in fiber insulation on three sides.
