Southwark Metal 27R_4X10X6 Sheet Metal Pipe Boot 4x10x6

Product Description

The SOUTHWARK METAL 27R_4X10X6 is a straight sheet metal pipe boot designed to transition from a rectangular duct opening to a round pipe collar in forced-air HVAC distribution systems. Constructed from hot dip galvanized steel, this register boot measures 4 inches by 10 inches at the register face (Size A) and accepts a 6-inch diameter round pipe collar at the outlet (Size B). It is manufactured to comply with ACCA and SMACNA standards, making it a code-appropriate choice for residential and light commercial duct fabrication and installation work performed by licensed HVAC technicians and sheet metal contractors.

This pipe boot is used where a rectangular floor, wall, or ceiling register opening must connect to a 6-inch round supply or return duct branch. The straight configuration suits installations where the duct run approaches the register boot without requiring an offset. It fits into standard new-construction and retrofit duct system layouts and is appropriate for use in residential forced-air systems as well as light commercial applications where SMACNA-compliant fittings are specified.

Key Features

• Hot dip galvanized steel construction resists corrosion in humid duct environments
• 4 inch by 10 inch register face (Size A) matches standard residential register and grille openings
• 6 inch diameter collar (Size B) connects directly to round duct pipe or flex duct with standard take-off fittings
• Straight configuration simplifies installation where duct alignment is direct
• Manufactured to ACCA and SMACNA applicable standards for duct system fittings

Compatibility

Designed as an OEM-style sheet metal fitting for use in forced-air HVAC duct systems requiring a 4 inch by 10 inch register opening with a 6-inch round collar connection, per ACCA and SMACNA duct fabrication standards.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors. The system should be powered down and the air handler shut off before fitting installation or duct modification. Secure the collar to round duct using sheet metal screws and approved duct sealant or mastic per SMACNA guidelines. Verify register face dimensions match the rough opening before securing the boot to the subfloor or framing.
