B-LINE 241212 SC NK – Frequently Asked Questions

1) Can a NEMA 1 junction box like the B-Line 241212 SC NK be used outdoors or in a washdown area?
No. The 241212 SC NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It offers no protection against rain, hose-down, dust ingress, or corrosive wet environments. For outdoor mounting or washdown, you need a Type 3R, 4, or 4X enclosure instead.
2) What are the actual box dimensions on the B-Line 241212 screw cover junction box?
It is a 24 inch by 12 inch by 12 inch box: 24 in height, 12 in width, and 12 in length/depth. That gives you a tall, deep gutter-style body with plenty of room for splices and wire bending space behind the cover.
3) Does this B-Line junction box come with knockouts already punched?
No knockouts. The SC NK designation means screw cover, no knockout, so the body ships blank and you punch or hole-saw your own conduit entries wherever the run needs them. Budget time for that on the install, and use the appropriate connectors and sealing washers for the openings you cut.
4) How does the screw cover mount, and can one person hang this box alone?
The cover is a screw-on type with plated screws and keyhole slots, so you can back the screws out part way, lift the cover onto the slots, and let it hang while you start the rest. The box itself is surface mounted through thru holes in the back and weighs 24.1 lb empty, so anchor into studs or use hardware rated for that load plus conductors.
5) What gauge steel is the B-Line 241212 junction box, and is it painted?
The body is carbon steel at 16 gauge, finished in painted ANSI 61 grey. That is the standard grey used across most industrial control enclosures, so it will match panels and gutters already on the wall in a typical plant or mechanical room.
6) Is this Eaton B-Line enclosure UL listed for a commercial or institutional job spec?
It is built to UL 50, the standard covering enclosures for electrical equipment, and it is a NEMA Type 1 indoor enclosure. It is also made in the US, which matters on public work with domestic sourcing requirements.
7) What is the exact part number to order this 24x12x12 B-Line screw cover box?
Order it as Eaton B-Line 241212 SC NK. The number reads directly as the dimensions plus the configuration: 24 x 12 x 12, screw cover, no knockout.
8) Is a screw cover junction box the right choice, or should I use a hinged door enclosure?
A screw cover box like the 241212 SC NK suits pull points, splice points, and terminal work you rarely open. Every access means backing out the plated screws, though the keyhole slots on the cover make that quicker. If the box will be opened routinely for adjustment or troubleshooting, a hinged-door Type 1 enclosure is the better fit.
