Southwark Metal 27R_2-1/4X10X6 Sheet Metal Pipe Boot

Product Description

The SOUTHWARK METAL 27R_2-1/4X10X6 is a straight sheet metal pipe boot designed for register-to-duct connections in residential and light commercial HVAC distribution systems. Fabricated from hot dip galvanized steel, this boot transitions from a 2.25 x 10 inch rectangular register opening to a 6 inch round duct collar. It serves as the final fitting between the branch duct and the floor, wall, or ceiling register. HVAC installers and sheet metal contractors use this fitting when roughing in forced-air supply or return runs where a round duct must terminate at a rectangular register face. The straight configuration keeps the collar perpendicular to the boot face, simplifying layout in standard stud and joist cavity runs.

This pipe boot is suited for new construction and retrofit forced-air installations where a 6 inch round branch duct connects to a 2.25 x 10 inch register opening. It is appropriate for residential single-family and light commercial occupancies using conventional sheet metal ductwork. The straight design works best in floor, sidewall, and ceiling register locations where the duct runs directly into the back of the register without an offset. Installers working to ACCA and SMACNA standards will find this fitting consistent with those guidelines for duct fabrication and installation practice.

Key Features

• Hot dip galvanized steel construction resists corrosion in crawlspace, slab, and attic installations
• Straight register type transitions a 6 inch round duct collar to a 2.25 x 10 inch rectangular register face
• Fabricated to ACCA and SMACNA applicable standards for sheet metal duct fittings
• Register boot configuration accepts standard 2.25 x 10 inch floor or wall register grilles
• Galvanized finish is compatible with standard duct tape, mastic, and sheet metal screw fastening methods

Compatibility

Designed as an OEM-style sheet metal fitting for forced-air HVAC systems using 6 inch round branch ducts terminating at 2.25 x 10 inch rectangular register openings, per ACCA and SMACNA duct construction standards.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor following SMACNA duct construction guidelines and applicable local mechanical codes. The system should be powered down and, for heating applications, the furnace or air handler shut off before disturbing existing ductwork. Seal all joints with listed duct mastic or UL 181-rated tape and secure with sheet metal screws to prevent air leakage at the boot connection. Do not compress or restrict the round collar inlet, as reduced cross-section will increase static pressure and reduce airflow at the register.
