Air Flow Products 7741005 Straight Register Boot 4x10 5in Collar

Product Description

The AIR FLOW PRODUCTS 7741005 is a straight register boot designed to connect round duct to a rectangular floor, wall, or ceiling register opening. The boot features a 4x10 inch face opening and a 5 inch round collar for duct attachment. This type of fitting is a standard component in residential and light commercial forced-air distribution systems. HVAC installers use it to terminate a duct run at the register location, providing a clean transition from round flex or rigid duct to the register face plate.

This boot is suited for new construction and retrofit applications where a straight-style transition is required between the supply duct and the register opening. It is commonly installed in floor, sidewall, or ceiling register locations depending on the duct layout. The 4x10 inch face size is one of the most common register dimensions used in residential forced-air systems, making this boot a frequent choice for standard residential duct installations.
