Cody Company 645R68128 Slant Top Register Boot

Product Description

The CODY COMPANY 645R68128 is an insulated slant top register boot designed for use in residential and light commercial HVAC duct systems. A register boot connects the duct run to the floor, wall, or ceiling register, and the slant top configuration allows for angled transitions where straight drops are not practical. The built-in insulation helps reduce heat loss and condensation along the boot body, maintaining system efficiency at the supply point. This fitting is typically installed by HVAC technicians and sheet metal contractors during new construction or duct replacement work.

The 645R68128 is suited for residential forced-air heating and cooling systems where an angled or offset duct-to-register transition is required. The slant top design accommodates installations where floor joists, framing members, or other structural elements prevent a direct vertical drop. The insulated construction makes it appropriate for unconditioned spaces such as crawl spaces, basements, and attics where thermal performance at the boot is a priority.

Key Features

• Slant top configuration allows angled duct-to-register transitions
• Integrated insulation reduces heat loss and limits condensation at the boot
• Designed for floor, wall, or ceiling register connections in forced-air systems
• Suitable for use in unconditioned spaces where thermal performance matters

Compatibility

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

Installation Notes

Installation should be performed by a qualified HVAC technician or sheet metal contractor. Shut down the air handler and confirm the system is de-energized before working on the duct. Seal all connections with approved foil tape or mastic sealant per local mechanical code requirements. Support the boot securely to the framing structure to prevent movement and air leakage at the register collar.
