Seal-tite 1279-24-041006 Elbow Register Boot 4x10x6

Product Description

The SEAL-TITE 1279-24-041006 is a 4 inches x 10 inches elbow register boot with a 6-inch collar, designed for basement and ceiling register installations in residential forced-air HVAC duct systems. The boot features a 90-degree elbow configuration that transitions from round duct to a rectangular register face, making it suitable for runs where the supply duct approaches the register from below or from an overhead plenum. The 4-inch rails support secure register seating and alignment. Licensed HVAC technicians and sheet metal contractors handle installation as part of new construction or duct retrofit work.

This elbow boot is used in residential applications where supply air must be directed through a floor, basement ceiling, or overhead ceiling plane to a standard 4 inches x 10 inches register face. The elbow geometry accommodates tight duct routing typical in finished basements, drop ceilings, and joist-bay duct runs. The 4-inch rails allow the register grille to seat flush and stay aligned after installation, reducing air bypass around the register face.

Key Features

• 4 inches x 10 inches register face opening sized for standard residential supply registers
• 6-inch round collar for round duct connection
• 90-degree elbow configuration for basement and ceiling register transitions
• 4-inch rails provide positive register seating and alignment
• Suited for new construction and duct retrofit installations

Compatibility

Designed as an OEM-style replacement and new-construction fitting for residential forced-air duct systems requiring a 4 inches x 10 inches elbow register boot with a 6-inch round collar inlet.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal contractors. Shut down the air handler or furnace and confirm the system is de-energized before cutting into existing ductwork or modifying the plenum. Secure the boot to the duct collar with sheet metal screws and seal all joints with listed duct mastic or UL 181-rated foil tape per local mechanical code requirements. Confirm the register face sits flush against the boot rails before fastening the grille.
