Lukjan rb302105 90 Degree Perimeter Register Boot

Product Description

The LUKJAN rb302105 is a 90-degree elbow register boot designed to transition a 5-inch round duct into a 2-1/4-inch wide perimeter floor or wall register opening. Formed from 30-gauge galvanized steel, this boot delivers a precise fit for standard perimeter register layouts in residential and light commercial duct systems. The 10-inch boot length supports proper alignment between the duct run and the register face, and the galvanized steel construction resists corrosion for long-term service. HVAC installers and sheet metal contractors reach for this boot when terminating supply duct runs at floor or baseboard register locations.

This boot is suited for residential forced-air heating and cooling systems as well as light commercial applications where a 5-inch round supply duct must terminate at a perimeter register. The 90-degree elbow configuration routes airflow from a horizontal or vertical duct run directly into a floor or low-sidewall register opening. It fits standard 2-1/4-inch by 10-inch perimeter register openings and is a common component in new construction and retrofit duct work.

Key Features

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Power down the air handler and confirm the system is de-energized before cutting into or connecting duct sections. Seal all joints with UL-listed duct sealant or foil tape per local mechanical code requirements. Secure the boot to the floor or wall framing per the applicable mechanical code before attaching the register face.
