Hoffman A20H16BLP3PT Wall Mount Enclosure Type 4

Product Description

The HOFFMAN A20H16BLP3PT is a wall mount electrical enclosure built for indoor and outdoor industrial and commercial applications. Constructed from mild steel with a gray finish, this enclosure measures 20 inches tall by 16 inches wide by 8 inches deep. It features a continuous hinge door design combined with a 3-point latch system for secure, consistent closure across the full door perimeter. Licensed electricians and industrial maintenance technicians use this enclosure to house control components, terminal blocks, and other electrical equipment requiring protection from dust, water, and environmental contaminants.

This enclosure is suited for panel-building, machine control, and general electrical distribution applications in both residential and commercial settings. The Type 4 rating makes it appropriate for indoor or outdoor use where protection against windblown dust, rain, splashing water, and hose-directed water is required. It is commonly installed on walls in manufacturing facilities, mechanical rooms, and utility areas where a robust, weather-resistant housing is needed.
