Southwark Metal 51F6127SD Register Boot 12x6x7

Product Description

The SOUTHWARK METAL 51F6127SD is a 601 series register boot designed for use in residential and light commercial forced-air HVAC duct systems. This sheet metal fitting connects the trunk line or branch duct to a floor, wall, or ceiling register, transitioning airflow to the conditioned space. The 51F6127SD measures 12 inches by 6 inches by 7 inches, making it a standard-fit component for common duct layouts. It is installed by HVAC technicians and sheet metal workers during new construction and retrofit applications.

The 51F6127SD is suited for residential forced-air systems where a 12-by-6-inch duct opening transitions to a 7-inch collar or register opening. The 601 series designation identifies a standard register boot profile widely used in residential duct fabrication. This fitting is appropriate for floor, side-wall, or toe-kick register installations depending on orientation at rough-in.

Installation Notes

Register boots are installed by licensed HVAC technicians or sheet metal workers as part of the supply duct system. Power down the air handling unit and close the fuel supply before working on any connected duct system. Secure the boot with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per local mechanical code requirements. Verify register opening dimensions match the boot face before fastening the grille.
