Air Flow Products 7741206 Straight Register Boot 4x12 6in Collar

Product Description

The AIR FLOW PRODUCTS 7741206 is a straight register boot designed to connect duct runs to floor, wall, or ceiling registers in residential and light commercial HVAC systems. This boot features a 4x12 inch opening and a 6 inch round collar, providing a direct transition from round ductwork to a rectangular register face. HVAC installers and sheet metal contractors use this fitting to terminate supply air runs cleanly and maintain proper airflow distribution through the register grille.

This straight register boot is suited for new construction and retrofit installations where a direct, in-line connection is required between the supply duct and the register. The 4x12 inch face pairs with standard 4x12 floor or wall registers, and the 6 inch collar accepts standard round flexible or rigid duct. It is commonly used in residential forced-air systems with gas, electric, or heat pump equipment.

• 4x12 inch rectangular opening fits standard 4x12 registers
• 6 inch round collar for connection to round supply ductwork

Compatibility

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal installer in accordance with local mechanical codes and SMACNA ductwork standards. Shut down and lock out the air handling unit before cutting into or modifying any duct section. Secure the collar connection to the round duct with sheet metal screws and seal all joints with approved mastic or UL 181-rated foil tape to prevent air leakage. Ensure the boot is properly supported to avoid stress on the register face or duct connection.
