Value Collection 57221061 Galvanized Duct Straight Stack Boot

Product Description

The VALUE COLLECTION 57221061 is a galvanized steel straight stack boot designed for rectangular-to-round duct transitions in residential and light commercial HVAC supply systems. The fitting measures 6 inches in inside diameter and 10 inches in overall length, with a standard 2.25-inch wide profile that fits flush against floor or wall framing. Fabricated from galvanized steel, this boot resists corrosion in the moist air conditions common inside supply ductwork. HVAC technicians and sheet metal installers use this fitting to connect round trunk or branch duct runs to floor or wall register openings.

Straight stack boots are installed where a vertical or near-vertical supply duct transitions to a horizontal register opening in a floor or sidewall stack application. This fitting is suited for standard residential forced-air systems using round duct branch runs. The 6-inch inside diameter accommodates common residential branch duct sizing, and the 2.25-inch width fits standard stud-bay or joist-bay rough openings. This boot is sold individually and is appropriate for new construction, renovation, and ductwork repair work.

Compatibility

Designed as a standard straight stack boot fitting for residential and light commercial forced-air supply duct systems using 6-inch round branch ductwork terminating at floor or wall register openings.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified sheet metal worker. Shut down the air handler or furnace and verify the system is de-energized before cutting into existing ductwork. Secure the boot to the duct branch with sheet metal screws and seal all joints with listed duct sealant or UL 181-rated tape per applicable mechanical codes. Do not rely on friction fit alone to maintain the connection under system operating pressure.
