Southwark 20" x 25" Single Wall Galvanized Return Air Box

Description

The Southwark return air box measures 20" x 25" and is made of single-wall galvanized steel. It forms the plenum between return ductwork and a wall or ceiling grille, helping air move back to the heating and cooling equipment smoothly.

Flanged edges and a flat sheet-metal back make duct connections quick and secure. The box holds a standard air filter, so filter changes are simple in residential and light commercial systems.
