Southwark Metal 731010 Return Air Box 10x10

Product Description

The SOUTHWARK METAL 731010 is a non-insulated return air box designed for residential and light commercial HVAC duct systems. Return air boxes connect the return air grille opening to the main duct system, drawing conditioned space air back to the air handler or furnace for reconditioning. This unit is built to a 10 x 10 inch nominal opening size. It is installed by licensed HVAC technicians and sheet metal contractors as part of a complete duct assembly during new construction or retrofit work.

The 731010 is suited for return air applications in forced-air heating and cooling systems where a non-insulated box is appropriate. A 10 x 10 inch return air box is a common fit for residential single-room return drops and smaller light commercial return applications. It is typically used in interior locations where the duct run does not require thermal insulation at the box itself.

Key Features

• Non-insulated construction for interior return air duct applications
• 10 x 10 inch nominal opening size for standard grille and duct connections
• Designed for connection to return air grilles and main duct trunk lines
• Suitable for residential and light commercial forced-air HVAC systems

Compatibility

Designed as an OEM-style replacement or new-installation component compatible with standard 10 x 10 inch return air duct openings in residential and light commercial forced-air HVAC systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA standards and local mechanical codes. Power down the air handling system completely before making any connections to the duct system. Secure the box to framing and ductwork using appropriate sheet metal fasteners and seal all joints with listed duct sealant or metal-backed tape to prevent air leakage. Do not use this non-insulated box in unconditioned spaces where condensation or thermal loss would require an insulated assembly.
