Air Flow Products DB480 Metal Dryer Vent Box 2x4

Product Description

The AIR FLOW PRODUCTS DB480 is a metal dryer vent box designed for installation within standard 2x4 wall cavities. It creates a recessed space behind the dryer, allowing the appliance to sit flush against the wall without crimping or crushing the exhaust duct. A kinked or compressed dryer duct restricts airflow, increases drying times, and creates a lint accumulation point that raises fire risk. The DB480 addresses that by providing a code-friendly recessed connection point that keeps the transition duct clear and fully open. This type of dryer vent box is a standard component in residential laundry room rough-ins and remodels where space between the dryer and wall is limited.

The DB480 is suited for residential laundry installations where the dryer sits against an exterior or interior wall framed with standard 2x4 construction. It fits into a single stud bay and is used during new construction rough-in or during dryer closet remodels. Installers use it wherever a dryer must sit close to the wall and the standard exhaust tail creates a pinch point. The metal construction makes it appropriate for installations where combustible clearances and duct material requirements must meet local code.

Installation Notes

Installation is typically performed by a plumber, HVAC technician, or general contractor during rough-in or remodel. The dryer and any connected appliances should be unplugged and gas supply shut off before beginning work. Local mechanical codes and IRC requirements for dryer exhaust duct material, maximum duct length, and number of elbows should be followed. Verify the duct connection size matches the dryer exhaust outlet before securing the box in the wall cavity.
