Snappy p13-428 90 Degree Register Boot 4x12 8 Inch

Product Description

The SNAPPY p13-428 is a 90-degree galvanized steel register boot designed to transition from an 8-inch round duct to a 4-inch by 12-inch rectangular floor or ceiling register opening. Fabricated from galvanized steel for corrosion resistance, this fitting redirects airflow at a 90-degree angle and provides a flush mounting surface for a standard 4 x 12 floor or sidewall register grille. HVAC installers and sheet metal contractors use this boot during new construction and retrofit duct system work to terminate branch runs cleanly at the register opening.

This register boot is suited for residential forced-air heating and cooling systems where branch duct runs terminate at floor, wall, or ceiling registers. The 8-inch collar accepts standard 8-inch round flexible duct or rigid pipe, and the 4 x 12 rectangular neck matches commonly stocked register grilles. It is a straightforward replacement or new-installation fitting for light commercial and residential HVAC duct systems.

Key Features

• 90-degree elbow configuration routes duct airflow perpendicular to the register face
• 8-inch round collar connects directly to standard 8-inch round branch duct or flex duct
• 4 x 12 inch rectangular register opening accepts standard 4 x 12 grilles and registers
• Galvanized steel construction resists corrosion in typical residential duct environments
• Lightweight at 0.50 pounds for easy single-technician handling during installation

Compatibility

Designed as an OEM-style sheet metal fitting compatible with residential and light commercial forced-air duct systems using 8-inch round branch runs terminating at a 4 x 12 inch register opening.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors. Power down the air handler or furnace at the disconnect before making duct connections. Secure the 8-inch collar to the branch duct with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per applicable mechanical codes. Confirm the rectangular register opening is flush and properly supported before fastening the grille.
