Seal-tite 4272-041006 Oval Straight Register Boot 4x10 to 6 in

Product Description

The SEAL-TITE 4272-041006 is an oval straight register boot designed to transition from a 4-inch x 10-inch oval duct opening to a 6-inch round collar. This fitting connects ductwork to a floor, wall, or ceiling register in residential and light commercial HVAC systems. The straight-boot configuration keeps airflow on a direct path from the duct run to the register face, minimizing turbulence at the takeoff point. HVAC installers and sheet metal mechanics use this type of boot when running oval trunk lines or branch runs into standard register openings.

This register boot is suited for new construction and retrofit duct installations where a 4-inch x 10-inch oval branch must terminate at a 6-inch round collar feeding a floor or sidewall register. It fits into typical residential forced-air supply systems using oval duct configurations, which are common in low-clearance applications such as floor joists and tight plenum spaces.

Key Features

• Straight-boot design delivers direct airflow from oval branch to round register collar
• 4-inch x 10-inch oval inlet transitions to a 6-inch round collar outlet
• Suited for low-clearance duct runs where oval duct is required over round
• Compatible with standard 6-inch round register and grille collars

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial forced-air supply duct systems using 4-inch x 10-inch oval branch ductwork terminating at a 6-inch round register opening.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal mechanic. Shut down the air handling unit and confirm the system is depressurized before cutting into or connecting to existing ductwork. Seal all joints with UL-listed duct mastic or metal foil tape in accordance with local mechanical codes and SMACNA guidelines. Do not use standard cloth-backed duct tape as the sole sealant on supply duct connections.
