Seal-tite 1279-24-041005 Elbow Register Boot 4x10 in

Product Description

The SEAL-TITE 1279-24-041005 is a 4-inch by 10-inch, 5-degree elbow register boot designed for basement and ceiling duct termination applications. The boot transitions from round or rectangular duct to a flat register opening, directing conditioned air into the living space. It includes 4-inch mounting rails for secure attachment to floor joists, ceiling framing, or subfloor assemblies. HVAC installers use this boot as the final duct fitting before a floor or ceiling register cover is applied. The 5-degree elbow angle compensates for framing offsets and allows the register face to sit flush against the finished surface.

This register boot fits residential forced-air heating and cooling systems where ductwork terminates at a basement ceiling or finished floor. It is suited for new construction and retrofit installations where a 4-inch by 10-inch register opening is required. The included 4-inch rails simplify attachment to framing members, reducing installation time in both framed floor and drop-ceiling assemblies. Sheet metal and HVAC mechanics are the primary installers for this type of fitting.

Key Features

• 4-inch by 10-inch register opening matches standard 4 x 10 floor and ceiling grilles

• Integrated 4-inch mounting rails for attachment to joists or framing members
• Designed for basement ceiling and floor ceiling termination points in residential duct systems

Compatibility

Designed as an OEM-style replacement or new-install fitting for residential forced-air duct systems requiring a 4-inch by 10-inch elbow register boot at basement ceiling or floor termination points.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic. Shut down the air handler and confirm the system is de-energized before working on duct connections. Secure the boot to framing using the integrated rails and appropriate fasteners; seal all seams with UL 181-listed duct mastic or foil tape per local mechanical code requirements. Confirm the register opening is flush with the finished surface before attaching the grille or register cover.
