Air Flow Products 7741006 Straight Register Boot 4x10 6in Collar

Product Description

The AIR FLOW PRODUCTS 7741006 is a straight register boot designed to connect round duct to a rectangular floor, wall, or ceiling register in residential and light commercial HVAC systems. The boot features a 4x10 inch rectangular register opening and a 6 inch round collar for duct connection. This style of register boot is a standard component in forced-air distribution systems, bridging the transition from round flexible or rigid duct to the register face. HVAC installers and sheet metal contractors use this fitting during new construction rough-in and duct replacement work.

The 7741006 straight boot is suited for installations where the duct run approaches the register location in a straight, perpendicular path without requiring an offset or angled transition. The 4x10 inch face dimension is a common residential register size, making this boot compatible with standard 4x10 supply or return registers. The 6 inch collar accepts typical 6 inch round duct, including flexible duct with a draw band or sheet metal collar connection. It is used in floors, sidewalls, and ceiling applications depending on system layout.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with local mechanical codes. Power down the air handling unit at the disconnect before working on duct connections. Secure the round collar to flexible or rigid duct using sheet metal screws and foil tape or an approved draw band per local code requirements.
