Wall-mount enclosure for NEMA 4, 12, 13 environments

The HOFFMAN A404CHNF is a carbon-steel electrical box rated NEMA 4, 12 and 13 with an IP66 ingress rating. It suits indoor or outdoor installations that need protection from dust, water spray and oil. The 4.0 in height and 4.0 in width with 3.0 in depth provide a compact footprint for junction or terminal wiring.

Powder-coated steel with hinged cover and clamps

The gray powder-coated finish resists corrosion on the 14/16 ga steel body. A hinged solid cover secures with screw-down clamps and a neoprene gasket to maintain the seal. External wall-mounting brackets and included screws allow direct surface mounting without extra hardware.

Verify NEMA rating and depth before ordering

Confirm that NEMA 4, 12 and 13 meet the environmental demands of your application. The 3.0 in internal depth limits the size of terminal blocks or connectors that can fit inside. Ensure the mounting surface can support the steel enclosure and that the clamps provide the required sealing pressure.
