Air Flow Products 7731007 Straight Register Boot 3.25x10

Product Description

The AIR FLOW PRODUCTS 7731007 is a straight register boot designed to connect rectangular duct openings to floor, wall, or ceiling registers in residential and light commercial HVAC distribution systems. This boot transitions from a 3.25 by 10 inch rectangular duct opening and features a 7 inch round collar for connection to branch ductwork. The straight configuration maintains a direct airflow path from the duct collar to the register face, minimizing turbulence and static pressure loss at the supply or return termination point. HVAC installers and sheet metal contractors use this boot as a standard component in forced-air system rough-in and retrofit work.

This register boot is suited for residential forced-air heating and cooling systems where branch runs terminate at a floor, sidewall, or ceiling register. The 3.25 by 10 inch face dimension is a common residential register size, and the 7 inch round collar accommodates standard round flexible or rigid branch duct. It is appropriate for new construction rough-in as well as duct modification and replacement projects in existing homes and light commercial spaces.

Key Features

• Straight profile delivers a direct, low-restriction airflow path from collar to register opening
• 3.25 by 10 inch rectangular register face matches a common residential register size
• 7 inch round collar for connection to standard round branch ductwork
• Designed for floor, wall, or ceiling register termination points in forced-air systems

Compatibility

Designed as an OEM-style replacement or new-installation straight register boot for residential forced-air HVAC distribution systems using 3.25 by 10 inch registers with a 7 inch round branch duct connection.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Turn off the air handler or furnace and ensure the system is de-energized before beginning any duct work. Secure the 7 inch round collar to the branch duct using sheet metal screws and approved duct tape or mastic sealant per local mechanical code requirements. Set the boot in the framing opening and fasten to the subfloor, wall, or ceiling framing before installing the register face.
