The SOUTHWARK METAL 27R_6X12X6 is a straight sheet metal pipe boot designed to transition from round duct to a rectangular register opening in residential and light commercial HVAC duct systems. Constructed from hot dip galvanized steel, this boot connects a 6-inch diameter round collar to a 6-inch by 12-inch rectangular register face. It is used to terminate supply or return air runs at floor, wall, or ceiling register locations. HVAC installers and sheet metal tradespeople use this fitting when completing low-pressure forced-air distribution systems built to SMACNA and ACCA standards.
This pipe boot is suited for new construction and retrofit applications where a straight-style transition is required at the register end of a branch duct run. The straight configuration keeps the duct run in-line with the register opening, making it a common choice for floor-mounted and ceiling-drop installations. It fits standard 6-inch round branch ducts and terminates at a 6-inch by 12-inch register face, accommodating widely available residential register sizes.
Designed as an OEM-style sheet metal fitting for residential and light commercial forced-air duct systems requiring a straight pipe boot transition from 6-inch round duct to a 6-inch by 12-inch register opening.
Installation is performed by licensed sheet metal workers or HVAC technicians following SMACNA duct construction standards. Secure the round collar to the branch duct with sheet metal screws and seal all joints with listed duct sealant or metal-backed tape per local mechanical code requirements. Power down the air handling unit before making any connections in the duct system. Do not use this fitting to transition to registers with differing face dimensions.
