The GV0668 4 in. x 12 in. x 6 in. end boot is a key transition fitting engineered for modern heating, cooling, and ventilation networks. Fabricated from lightweight 32-gauge galvanized steel, this boot facilitates a right-angle transition at the termination point of a run. It connects a 6-inch round supply pipe smoothly to a 4-inch by 12-inch rectangular air register box or grill.
Commonly deployed by HVAC residential installers, this end boot is ideal for placement at the dead end of a joist space or wall cavity where a branch line terminates into a floor or wall vent. The 32-gauge structure offers an optimized balance of flexibility and rigidity for quick sheet metal installations. Its protective galvanized coating guards against rust and condensation, ensuring durable air delivery over years of system use.
Ensuring correct dimensional mapping between your round flexible or rigid pipe and the rectangular floor register prevents static pressure issues and air leakage. This end boot fits cleanly into standard structural frames and can be easily secured using sheet metal screws and sealed with mastic. Verify your layout configurations and sizing to integrate this functional GV0668 fitting into your system.
