Value Collection 77221050 Galvanized Straight Register Boot

Product Description

The VALUE COLLECTION 77221050 is a galvanized steel straight register boot designed for residential and light commercial duct distribution systems. It connects round duct to a rectangular floor, wall, or ceiling register opening, directing conditioned air into the living space. The boot features a 5-inch inside diameter inlet and an overall length of 10 inches, making it a standard-gauge fitting suitable for supply-side trunk-to-register transitions. HVAC installers and sheet metal contractors use this fitting during new construction and system retrofits.

This register boot is suited for residential forced-air heating and cooling applications where a round duct run must transition to a rectangular register face. The 2.25-inch by 10-inch collar configuration is a widely used sizing in residential duct layouts, fitting standard floor and wall register openings. It is typically installed at the end of a branch run where the duct terminates at a supply register grille.

Installation Notes

Straight register boots are installed by licensed HVAC technicians or sheet metal contractors in accordance with local mechanical codes and SMACNA duct construction standards. Power down the air handler and close the disconnect before working inside the duct system. Secure the boot to the branch duct using sheet metal screws and seal all joints with UL-listed foil tape or mastic sealant to minimize air leakage. Do not compress or restrict the inlet opening during framing or subfloor installation.
