Southwark Metal 28R_4X10X6 Pipe Boot Register 4x10 6in

Product Description

The SOUTHWARK METAL 28R_4X10X6 is a center-end sheet metal pipe boot designed to connect round duct to a rectangular register opening in residential and light commercial HVAC duct systems. Constructed from hot dip galvanized steel, it transitions from a 4 inch x 10 inch rectangular register face to a 6 inch round collar. The center-end configuration positions the round collar at the midpoint of the rectangular boot, making it suitable for floor, ceiling, or sidewall register applications where duct alignment calls for a centered takeoff. HVAC sheet metal installers and ductwork contractors are the primary tradespeople who specify and install this fitting.

This pipe boot register is used in forced-air heating and cooling distribution systems where a 6 inch round supply or return duct feeds a 4 inch x 10 inch register opening. It is commonly installed in residential new construction and retrofit ductwork, particularly in floor joist bays or framed ceiling cavities. The fitting meets applicable standards set by ACCA and SMACNA, making it appropriate for use in systems designed and installed to those specifications.

Key Features

• Hot dip galvanized steel construction provides corrosion resistance in typical duct environments
• Center-end collar orientation suits installations requiring centered duct alignment beneath the register face
• 4 inch x 10 inch rectangular opening mates directly to standard register grille sizes
• 6 inch diameter round collar connects to standard 6 inch round duct or flex duct
• Compliant with ACCA and SMACNA applicable standards for sheet metal ductwork fittings

Compatibility

Designed as an OEM-style sheet metal fitting for use with standard 6 inch round duct and 4 inch x 10 inch register grilles in residential and light commercial forced-air HVAC duct systems built to ACCA and SMACNA standards.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal ductwork installers. Shut down and de-energize the air handling system before cutting into existing ductwork or securing the boot in place. Secure the rectangular collar to the register frame and seal all joints with UL 181-rated duct sealant or mastic per local mechanical code requirements. Refer to SMACNA duct construction standards for fastener spacing and sealing requirements applicable to the system pressure class.
