Value Collection 57221261 Galvanized Straight Stack Boot 6 in

Product Description

The VALUE COLLECTION 57221261 is a galvanized steel straight stack boot designed for residential and light commercial HVAC duct systems. This fitting connects round duct to a floor or wall register opening, transitioning from a 6-inch inside diameter round duct to a flat stack outlet measuring 2.25 inches wide by 12 inches long. Built to standard gauge galvanized steel, it provides corrosion resistance suitable for supply-air distribution in forced-air heating and cooling systems. HVAC technicians and sheet metal installers use this boot when running vertical or horizontal duct runs to floor or sidewall registers in new construction and retrofit applications.

This straight stack boot is used in residential forced-air systems where duct runs terminate at a floor or baseboard register. The 6-inch ID inlet accepts standard 6-inch round duct, and the 2.25 x 12-inch flat outlet aligns with standard floor or wall register face dimensions. It is appropriate for new construction framing rough-ins and replacement work where an existing boot has corroded or become mechanically damaged. Sheet metal contractors and HVAC service technicians are the primary installers.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal contractor in accordance with local mechanical codes and SMACNA duct construction standards. Shut down the air handling system and verify the system is de-energized before disturbing existing ductwork. Secure the boot to round duct using sheet metal screws and seal all joints with UL-listed foil tape or mastic sealant to maintain system static pressure. Avoid sharp bends or kinks in flexible duct connections at the boot inlet.
