B-LINE 241210 SC NK – Frequently Asked Questions
1) Can the B-Line 241210 SC NK junction box be used outdoors or in a washdown area?
No. The 241210 SC NK is a NEMA Type 1 enclosure, which is indoor use only and offers no protection against rain, hose-down, or dust ingress. For a wet or outdoor location you need a Type 3R or Type 4 enclosure instead. It also has no knockouts and uses thru holes for mounting, so any conduit entry you cut is your own and unsealed.
2) What are the actual box dimensions of the B-Line 241210 SC NK enclosure?
It measures 24 inches high, 12 inches wide, and 10 inches deep, so it needs a clear wall area of 24 by 12 inches plus the 10 inch standoff into the room. That depth is generous for a pull or junction box, which is what makes it usable for larger conductor bends and terminal blocks rather than just splices.
3) Does this B-Line junction box come with knockouts, or do I have to punch my own conduit holes?
You punch your own. The 241210 SC NK is the no-knockout version, so every side and the back come blank and you locate conduit entries wherever the run lands. Plan on a knockout punch set and appropriate hole seals. If you would rather have factory openings, order a knockout-equipped screw cover box instead.
4) How does this box mount to the wall, and is any hardware included?
Mounting is surface, through holes in the back of the enclosure, so it fastens flat to a wall, backboard, or strut. The anchors or screws are not part of the box; pick fasteners for your substrate and rate them for the 21.7 lb empty weight plus whatever conductors and devices go inside. The cover itself uses keyhole slots and plated screws, so the cover can be lifted off without fully removing every screw.
5) Is the B-Line 241210 SC NK junction box UL listed for an inspected commercial job?
It is built to UL 50, the standard covering enclosures for electrical equipment, and carries a NEMA Type 1 rating for indoor use. That is the combination an inspector expects on a surface mounted indoor pull or junction box. It is also made in the US, which matters on public work with domestic sourcing requirements.
6) Is this a screw cover box or a hinged door enclosure?
Screw cover. The 241210 SC NK cover bolts on with plated screws and keyhole slots rather than swinging on hinges, which suits a junction or pull box you open rarely. If the box houses controls or terminations that get serviced regularly, a hinged-door enclosure is the better choice, since a screw cover has to be lifted clear and set aside each time.
7) What is this B-Line enclosure made of and what is the finish?
The shell is 16 gauge carbon steel with a painted finish in ANSI 61 grey, the standard gray used across most industrial control gear, so it blends with panels and gear already on the wall. Painted carbon steel is fine for dry indoor plant and mechanical rooms; for corrosive or damp areas look at stainless or a gasketed Type 4X enclosure instead.
8) What part number do I order for the 24 x 12 x 10 B-Line screw cover box with no knockouts?
The Eaton B-Line part number is 241210 SC NK. The digits read as the box size, 24 inch height by 12 inch width by 10 inch depth, with SC for screw cover and NK for no knockout. Quoting that full suffix matters, since the same size is built in knockout and hinged versions too.
