Air Flow Products 7741207 Straight Register Boot 4x12

Product Description

The AIR FLOW PRODUCTS 7741207 is a straight register boot designed to connect rectangular duct openings to floor, wall, or ceiling registers in residential and light commercial HVAC installations. This boot features a 4x12 inch face opening and a 7 inch round collar for duct attachment. Straight register boots are a standard component in forced-air distribution systems, providing a clean transition between the branch duct and the register face. HVAC installers and sheet metal contractors use this fitting during new construction and retrofit duct work.

This boot is suited for residential forced-air systems where a straight-style fitting is required at the register termination point. The 4x12 face dimension accommodates standard 4x12 registers commonly used in floor and sidewall applications. The 7 inch collar accepts round flexible duct or rigid round duct of the matching diameter, making it compatible with typical residential trunk-and-branch layouts and radial duct systems.

• 4x12 inch face opening fits standard 4x12 registers
• 7 inch round collar for round duct attachment

Compatibility

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified sheet metal contractor. The air handling system should be powered down and the air handler or furnace shut off before connecting or modifying any duct fitting. Secure the collar connection to the branch duct using approved sheet metal screws and foil-backed duct tape or mastic sealant per local mechanical code requirements. Verify register face alignment and secure the boot to the framing before attaching the register grille.
