The SEAL-TITE 1374-031006 is a 90-degree angle duct boot designed for residential and light commercial HVAC duct distribution systems. It features a 3-inch by 10-inch face opening, a 6-inch round neck, and a 2-inch extension that provides additional clearance during installation. Duct boots of this type connect the supply trunk or branch duct to a floor, wall, or ceiling register. HVAC installers and sheet metal contractors use these fittings to terminate duct runs cleanly at the register opening.
This boot is suited for residential forced-air heating and cooling systems where a 90-degree transition is required between the duct run and the register face. The 3-inch by 10-inch face dimension corresponds to a standard register size commonly found in residential new construction and retrofit applications. The 2-inch extension provides added flexibility when rough-in depths vary or when framing alignment requires additional offset at the termination point.
Designed as an OEM-style replacement or new-installation fitting for residential and light commercial forced-air duct systems using 6-inch round branch duct with a 3 x 10 inch register opening.
Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handler and, where applicable, the furnace or heat pump before making any duct connections. Secure the boot to the duct branch with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape in accordance with local mechanical codes. Verify that the face opening aligns flush with the finished floor, wall, or ceiling surface before securing the register.
