B-LINE 12104 HC NK – Frequently Asked Questions

1) Can the B-Line 12104 HC NK junction box be used outdoors or in a washdown area?
No. The 12104 HC NK is a NEMA Type 1 enclosure, which is indoor-only protection against incidental contact and falling dirt. It offers no rating against rain, hose-down, dust or oil, so keep it in dry indoor locations. For a wet or outdoor location you need a Type 3R, 4 or 4X enclosure instead.
2) Does this B-Line junction box come with knockouts for conduit?
No knockouts. The 12104 HC NK ships with a blank body, so you punch or drill your own conduit openings where the run actually lands. That is the point of the NK version. If you want factory conduit openings, order a knockout-equipped enclosure instead.
3) Is this enclosure UL listed for a commercial or institutional spec job?
The 12104 HC NK is built to UL 50, the standard covering enclosures for electrical equipment, and it is made in the US. If the drawing calls for a UL 50 Type 1 steel junction box, this answers that line.
4) What are the box dimensions on the B-Line 12104 HC NK enclosure?
It measures 12 inches high, 10 inches wide and 4 inches deep. The 4 inch depth is what usually decides the job: it gives you room for terminal blocks, small relays or wire splicing, but it is tight for anything with a deep back-of-panel projection.
5) Is the cover hinged or screw-on, and can it be taken off completely?
Both, in effect. The cover is hinged for quick access during service, and it is also removable, with a recessed pull ring and a friction dimple to hold it shut. Handy when you need the door out of the way entirely to land conduit or pull wire.
6) How does this junction box mount to the wall?
Surface mount, using thru holes in the back of the box. You fasten straight to the wall or strut with your own hardware; no mounting feet or brackets are part of the box. At 7.4 pounds empty, two-point anchoring into solid backing is enough for most installs, though masonry needs appropriate anchors.
7) What is the B-Line 12104 HC NK made of, and what color does it arrive in?
16 gauge carbon steel, painted ANSI 61 grey. That is the standard grey used across most industrial control enclosures, so it matches existing panels on a plant wall without repainting. Steel means it needs to stay in dry indoor areas to avoid corrosion.
8) Is a hinged-cover box like this better than a screw-cover junction box?
For anything you open more than once, yes. A hinged cover swings clear and stays captive, so there are no loose screws or dropped lids when you are working in a ceiling or on a ladder. Screw-cover boxes suit pull points you never revisit. This one also lifts off fully when you need full body access, and the friction dimple keeps it closed between service calls.
