Southwark Metal 91_10X12 Floor Register Duct Box 10x12

Product Description

The SOUTHWARK METAL 91_10X12 is a sheet metal duct box designed for floor register applications in residential and light commercial forced-air HVAC systems. Constructed from hot dip galvanized steel, this duct box measures 10 inches by 12 inches with an 11-inch depth, providing a durable transition point between the ductwork and the floor register grille. The galvanized finish resists corrosion and suits installations in slab, subfloor, and raised-floor environments. Licensed HVAC technicians and sheet metal contractors are the primary installers for this type of fitting.

This duct box is suited for floor-mounted register installations where a defined boot depth is required to accommodate subfloor framing or floor assembly thickness. The 10-inch by 12-inch face dimension aligns with standard floor register grille sizing, making it a straightforward fit in new construction and retrofit ductwork layouts. It conforms to ACCA and SMACNA applicable standards, making it appropriate for installations where compliance documentation is required.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in floor-level installations
• 10 inches x 12 inches face opening matches standard floor register grille dimensions
• 11-inch depth accommodates typical subfloor and floor assembly thicknesses
• Meets ACCA and SMACNA applicable standards for sheet metal ductwork

Compatibility

Designed as an OEM-style replacement or new-construction component for floor register applications requiring a 10-inch by 12-inch duct box opening in forced-air HVAC systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handling system and verify the supply or return is de-pressurized before fitting or sealing the duct box. Seal all joints with code-approved mastic or foil tape to prevent air leakage at the register boot connection. Secure the box to framing members per local code requirements before setting the floor finish and register grille.
