Enclosure for wall-mounted wiring

The HOFFMAN A6R64 is a carbon-steel electrical enclosure rated NEMA 3R and IP32 for indoor or sheltered outdoor use. It suits installers who need a compact junction box with a solid screw-on cover and integrated mounting holes. The galvanized grey finish resists corrosion in damp environments.

Fits standard conduit and device layouts

A 6 in by 6 in footprint with 4 in depth accepts common conduit entries while leaving room for terminal blocks or small relays. Captive screws on the cover prevent lost hardware during maintenance, and the included mounting holes allow direct wall attachment without extra brackets. The 12/14/16 ga construction provides rigid support for internal components.

Holds seal and structure under continuous exposure

The gasketed screw-latch cover maintains its IP32 rating through repeated opening cycles and temperature swings. Galvanized steel resists rust where condensation forms, and the UL50/50E and cUL listings confirm the enclosure meets sustained-load safety requirements. Screw fasteners stay tight under vibration from nearby equipment.

Questions about this item

What NEMA rating limits outdoor exposure for this enclosure?

The enclosure carries a NEMA Type 3R rating, meaning it is suitable for outdoor use where falling rain and sleet occur but not for submersion or directed water jets.

How much heat can the carbon-steel body dissipate when mounted in direct sun all day?

Carbon steel with a galvanized gray finish absorbs solar heat; without internal ventilation or a sun shield the internal temperature will rise well above ambient during sustained daytime exposure.

Which mounting hardware must be supplied separately to secure the box to a wall?

The enclosure includes captive cover screws and pre-drilled mounting holes, but lag bolts, anchors or self-tapping screws for the mounting surface are not included.
