Snappy 5-326 Straight Stack Boot 3.25x12 in 6 in Galvanized

Product Description

The SNAPPY 5-326 is a galvanized straight stack boot designed for residential and light-commercial HVAC duct systems. This fitting transitions from a rectangular duct opening to a round collar, allowing supply air to connect from a floor or wall stack to a register boot. The 3.25 x 12 inch rectangular inlet mates to a 6 inch round collar. Fabricated from galvanized steel for corrosion resistance and long service life, this boot is a standard component in forced-air distribution systems. HVAC installers and sheet metal technicians use it during new construction and duct retrofit work.

This stack boot is suited for floor, wall, or toe-kick register installations in residential forced-air systems. It is commonly used where a vertical or horizontal duct run terminates at a supply register location. The straight configuration keeps the airflow path direct, minimizing static pressure loss at the boot. The 3.25 x 12 inch face size matches standard floor register cutout dimensions widely used in residential construction.

Key Features

• Galvanized steel construction resists corrosion in typical duct environments
• Straight boot design maintains direct airflow path to the register
• 3.25 x 12 inch rectangular inlet matches common floor register openings
• 6 inch round collar connects to standard 6 inch round duct or flex duct
• Lightweight at 0.50 pounds for easy single-technician handling during installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 6 inch round duct systems using a 3.25 x 12 inch rectangular boot opening in residential forced-air HVAC applications.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal installer. Power down the air handler or furnace at the disconnect before working on the duct system. Secure the boot to the duct collar using sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per local mechanical code requirements. Do not use standard cloth duct tape as a permanent sealant.
