Cody Company 645R66127 Insulated Register Boot

Product Description

The CODY COMPANY 645R66127 is an insulated slant top register boot designed for use in forced-air duct distribution systems. This fitting connects the supply duct to a floor or wall register opening, with a slant-top profile that accommodates angled subfloor or framing conditions. The insulated construction limits heat transfer through the boot body, helping maintain conditioned air temperature between the air handler and the register face. HVAC installers and sheet metal contractors are the primary trades that work with this component.

This register boot is suited for residential and light commercial forced-air heating and cooling installations where standard straight-top boots cannot be used due to framing constraints or floor angle. The slant top design makes it a common choice in new construction and remodel work where joist bays or wall cavities require a non-perpendicular duct transition to the register. Insulation is particularly relevant in unconditioned spaces such as crawlspaces or basement ceilings where thermal loss from uninsulated boots is a service concern.

Key Features

• Slant top profile accommodates angled framing and subfloor installations
• Insulated body reduces heat transfer and limits condensation in unconditioned spaces
• Designed as a supply duct termination fitting connecting ductwork to a register opening
• Suitable for residential and light commercial forced-air systems

Compatibility

Designed as an OEM-style replacement or new-construction fitting for residential and light commercial forced-air supply duct systems requiring a slant top register boot termination.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal contractors. Shut down the air handling system and verify power is off before cutting into existing ductwork or modifying supply runs. Seal all connections with approved duct mastic or UL 181-listed tape per local mechanical code requirements. Secure the boot firmly to framing before attaching the register face to prevent air bypass at the opening.
