Southwark Metal 27R_4X14X8 Sheet Metal Pipe Boot Straight

Product Description

The SOUTHWARK METAL 27R_4X14X8 is a straight sheet metal pipe boot designed to transition from round duct to a floor or wall register opening in residential and light commercial HVAC duct systems. Fabricated from hot dip galvanized steel, this boot measures 4 inches by 14 inches at the register face (Size A) and connects to an 8-inch diameter round duct at the collar (Size B). The galvanized construction resists corrosion in both conditioned and unconditioned spaces. HVAC installers and sheet metal contractors use this fitting to terminate supply or return duct runs at a register plate. It meets ACCA and SMACNA fabrication standards, making it suitable for jobs where compliance documentation is required.

This pipe boot is used in forced-air heating and cooling systems where a round duct transitions to a rectangular register opening. The straight configuration suits installations where the duct drops or runs directly perpendicular to the floor or wall surface. Typical applications include new construction and retrofit duct work in residential homes and light commercial buildings. The 4 x 14 inch face accommodates standard register grilles of that size, and the 8-inch round collar connects directly to matching round duct or flexible duct with an appropriate clamp or draw band.

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. Power down the air handling unit and close the system before cutting into existing ductwork. Secure the round collar to the duct with sheet metal screws and seal all joints with UL-listed duct sealant or foil tape rated for HVAC use.
