Southwark Metal 24R_4X10X7 Pipe Boot Elbow 4x10 7in 90 Degree

Product Description

The SOUTHWARK METAL 24R_4X10X7 is a 90-degree sheet metal pipe boot elbow designed to transition ductwork to a floor, wall, or ceiling register opening. Fabricated from hot dip galvanized steel, this fitting connects a 7-inch round duct to a 4-inch by 10-inch rectangular register face. The 90-degree elbow geometry allows the round duct run to turn and terminate flush at a register opening without additional fittings. HVAC sheet metal contractors and installers use this boot in residential and light commercial forced-air distribution systems where a round trunk or branch connects to a standard rectangular register boot location.

This boot elbow is suited for supply-air applications in low-pressure forced-air systems. It is typically installed at the end of a branch run where the round duct meets the subfloor, wall cavity, or ceiling plane. The 4-inch by 10-inch register face matches a common standard register and grille size, making it a straightforward drop-in solution during new construction or duct retrofit work. Installation follows ACCA and SMACNA guidelines for residential and light commercial sheet metal ductwork fabrication and installation.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor following SMACNA and ACCA duct construction standards. Power down the air handler or furnace at the disconnect before making final duct connections. Secure the round collar to the branch duct with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per local mechanical code requirements. Ensure the register face is flush and fully supported at the floor, wall, or ceiling opening before fastening the grille or register.
