Hoffman A36R3612NK – Frequently Asked Questions

1) Is the Hoffman A36R3612NK enclosure rated for outdoor use?
Yes, the A36R3612NK carries a NEMA 3R rating, which covers outdoor installations where the box has to shed rain, sleet and external ice formation. That is a weather-shedding rating, not a washdown or dust-tight one, so if the location sees hose-down cleaning, windblown dust, or standing water, step up to a NEMA 4 or 4X enclosure instead.
2) Does a screw cover enclosure work if electricians need to get into the box regularly?
Not well. The A36R3612NK uses a screw-secured cover, which means removing and reinstalling fasteners every time the box is opened. It is a cost-effective closure for terminations, splices, and equipment you rarely touch. For panels needing daily or frequent access, specify a hinged-cover or latching continuous-hinge enclosure in the same NEMA rating.
3) Will a galvanized steel NEMA 3R enclosure hold up outdoors in a coastal or chemical environment?
The A36R3612NK is galvanized steel with an ANSI 61 gray polyester powder coat, a combination that handles general outdoor and industrial exposure and resists chipping, scratching, and fading. In salt-spray coastal air or around corrosive chemicals, galvanized steel is not the right call. Specify a 304 or 316 stainless or a fiberglass enclosure for those locations.
4) Does the A36R3612NK come with knockouts or a mounting panel?
It is a blank screw cover enclosure body and cover. Conduit entries are field-drilled or punched where you need them, and an interior mounting panel is a separate item ordered to the 36 x 36 body size. Plan hub or fitting selection to preserve the NEMA 3R rating, raintight fittings at the top and sides.
5) What is the exact Hoffman part number for the 36x36x12 NEMA 3R screw cover enclosure?
Hoffman A36R3612NK. The number reads out as the size and style: 36 x 36 body, 12 inch depth, R for the 3R rain-tight screw cover family. Use that full designation when ordering so you do not end up with the 4 or 4X version of the same footprint.
6) Will the Hoffman A36R3612NK match the gray enclosures already on my site?
Most likely, yes. The finish is ANSI 61 gray, the standard light gray used across industrial control and enclosure products, so it reads the same as other ANSI 61 boxes on a wall or skid. Hoffman also uses the same ANSI 61 gray across its steel enclosure lines.
