Southwark Metal RABR8121212 Return Air Box R8 Insulation 12 Inches X 12 Inches X 12 Inches

Product Description

The Southwark Metal RABR8121212 is a return air box designed for residential and light commercial HVAC duct systems. It measures 12 inches x 12 inches x 12 inches and comes with R8 insulation built in. Return air boxes are used where a return air grille connects to the duct system. They provide a clean, secure transition point that helps the system pull air back to the air handler or furnace efficiently. This unit is part of Southwark's RAB product family and is built for HVAC installers and sheet metal contractors who need a reliable, ready-to-install component. The box is constructed from 26-gauge galvanized steel, which resists corrosion and holds up well in attics, crawl spaces, and wall cavities. The galvanized coating protects the metal from moisture that is common in return air applications. The R8 insulation rating helps reduce energy loss and limits condensation on the exterior of the box. This is especially important in humid climates or when the return air box passes through unconditioned spaces like attics. The non-flanged design keeps installation straightforward and compatible with standard return air grille setups. Because it is manufactured in the USA, lead times tend to be more predictable for domestic HVAC projects. HVAC technicians and installers looking for an insulated return air box, galvanized sheet metal air box, or R8 return air plenum will find this unit meets common residential system specs. It weighs approximately 3.88 pounds, making it easy to handle during installation. Southwark Metal is a well-established name in HVAC sheet metal fabrication, and the RABR8121212 reflects their standard for quality and consistency in duct system components.
