Air Flow Products 7741408 Straight Register Boot 4x14 8in Collar

Product Description

The AIR FLOW PRODUCTS 7741408 is a straight register boot designed to connect ductwork to a floor, wall, or ceiling register opening. It provides a clean, direct transition from round duct to a rectangular register face, maintaining airflow direction without offset. The boot features a 4x14 inch rectangular register opening and an 8 inch round collar for duct attachment. It is used in residential and light commercial HVAC systems and is typically installed by HVAC technicians or experienced mechanical contractors during new construction or duct replacement work.

This straight register boot is suited for installation in forced-air heating and cooling systems where a direct, in-line duct-to-register connection is required. The 4x14 inch face dimension accommodates standard register and grille sizes in that profile, while the 8 inch collar accepts standard round duct or flexible duct of that diameter. It is appropriate for floor, sidewall, or ceiling register applications depending on system layout and installation orientation.

Installation Notes

Register boots are installed by licensed HVAC technicians or qualified mechanical contractors as part of a duct distribution system. Power down the air handler or furnace and close the system dampers before beginning any duct modification or boot installation. Secure the collar connection to round duct or flexible duct using sheet metal screws and foil-backed tape or mastic sealant in accordance with local mechanical codes.
