The SOUTHWARK METAL 24R_4X10X6 is a sheet metal pipe boot elbow designed to transition from a round duct to a floor or wall register opening. Constructed from hot dip galvanized steel, this fitting combines a 4 inch x 10 inch register boot with a 6 inch diameter round collar and a 90-degree elbow configuration. It is used in residential and light commercial forced-air HVAC systems to connect round supply duct to a rectangular register face. Licensed HVAC technicians and sheet metal installers are the typical trade installing this component during new construction or duct renovation work.
This fitting is suited for supply-air duct runs that require a directional change at the point of termination, particularly in floor or sidewall register applications. The 4 inch x 10 inch register face dimension is a common residential supply register size, and the 6 inch round inlet accommodates standard round branch duct. The 90-degree elbow allows the duct to change direction cleanly at the register location without additional fittings. It is appropriate for use in low-pressure residential supply systems built to ACCA and SMACNA standards.
Designed as an OEM-style sheet metal duct fitting for residential and light commercial forced-air HVAC supply systems using 6 inch round branch duct and 4 inch x 10 inch register openings, built to ACCA and SMACNA standards.
Installation is performed by licensed HVAC technicians or qualified sheet metal workers. Power down the air handling system at the disconnect before beginning any duct work. Secure the round collar to the branch duct using sheet metal screws and approved duct sealant or mastic in accordance with SMACNA installation guidelines. Support the fitting per local mechanical code requirements to prevent stress on adjoining ductwork.
