Southwark Metal 24R_4X10X4 Pipe Boot Elbow 4x10 to 4in

Product Description

The SOUTHWARK METAL 24R_4X10X4 is a sheet metal pipe boot elbow designed to transition from a rectangular register opening to a round duct collar at a 90-degree angle. Fabricated from hot dip galvanized steel, this fitting provides corrosion resistance suited to residential and light commercial HVAC duct systems. The rectangular inlet measures 4 inches by 10 inches and connects to a 4-inch round collar outlet. HVAC installers use this fitting to route supply air from a trunk line or branch duct up through a floor or wall register boot. It meets ACCA and SMACNA applicable standards for sheet metal ductwork fabrication.

This pipe boot elbow is used in forced-air heating and cooling systems where a floor or wall register requires a round-to-rectangular transition at a 90-degree turn. Typical installations include residential new construction and retrofit duct systems where branch runs terminate at a floor register. The 4-inch by 10-inch face matches standard register and grille sizing, while the 4-inch round collar accepts standard round duct pipe or flexible duct for a direct connection to the branch run.

Installation Notes

This fitting is typically installed by licensed HVAC technicians or sheet metal contractors during duct system rough-in or retrofit work. Power down the air handling unit and close the system before cutting into existing ductwork. Seal all joints with UL-listed duct sealant or metal foil tape in accordance with SMACNA standards. Use sheet metal screws to secure the boot to the subfloor or framing and verify the register face is flush and properly supported before finishing.
