Imperial GV0683-A Register Boot 3.25x10 to 4 Inch 30GA Galvanized

Product Description

The IMPERIAL MFG GROUP USA INC GV0683-A is a galvanized steel register boot designed to transition from a 3-1/4 inch by 10 inch rectangular duct opening to a 4 inch round collar. Constructed from 30-gauge galvanized steel, this boot provides a secure, corrosion-resistant connection point at the end of a duct run, where a floor, wall, or ceiling register is mounted. It is a standard component in residential forced-air HVAC systems and is typically installed by licensed HVAC technicians or sheet metal workers during new construction or duct replacement work.

This register boot is suited for residential HVAC duct systems that use 3-1/4 inch by 10 inch rectangular branch ducts feeding into a 4 inch round takeoff. The 3-1/4 by 10 inch profile is a common narrow-profile duct size used in floor joist bays and interior wall cavities. The 4 inch round collar connects directly to flexible or rigid round duct. This boot is sold in packages of 15 units, making it practical for new construction or multi-room duct installations.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal mechanic. The air handling system should be fully powered down and the system fan disabled before fitting or securing any duct components. The boot is secured to the duct branch using sheet metal screws and sealed with UL 181-rated duct mastic or metal foil tape per local mechanical codes. Do not use standard cloth duct tape as a primary sealant.
