Southwark Metal 91_6X12 Sheet Metal Duct Box 6x12

Product Description

The SOUTHWARK METAL 91_6X12 is a rectangular sheet metal duct box designed for floor register applications in residential and light commercial HVAC duct systems. Fabricated from hot dipped galvanized steel, this duct box delivers corrosion resistance suited to subfloor environments where moisture exposure is common. The rectangular profile measures 6 inches by 12 inches and is built to align with standard floor register openings. HVAC installers and sheet metal contractors use this type of duct box to transition from the supply duct run to the finished floor register, providing a clean, code-compliant termination point for conditioned air delivery.

This duct box is used in forced-air heating and cooling systems where floor-mounted supply registers are specified. It is a standard component in new construction and retrofit installations where ductwork terminates at floor level in residential or light commercial spaces. The rectangular form factor accommodates a 6 inch by 12 inch floor register opening. Installation typically occurs during the rough-in phase of HVAC work, with the box secured to the subfloor framing before finish flooring is applied.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal contractors following SMACNA and ACCA ductwork standards. Power down the air handling equipment before connecting or modifying any duct components. Secure the duct box to subfloor framing prior to finish flooring installation to ensure a flush, airtight fit at the register opening. Seal all joints with approved duct sealant or mastic to minimize air leakage in accordance with local mechanical codes.
