B-LINE 444 SC NK – Frequently Asked Questions

1) Can the B-Line 444 SC NK junction box be used outdoors or in a washdown area?
No. The 444 SC NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It has no gasket and no rating against water, oil, or dust. For a wet location or an outdoor wall you need a Type 3R or Type 4 enclosure instead.
2) Does the B-Line 444 junction box come with knockouts for conduit?
No knockouts. The 444 SC NK is a no-knockout box, so you drill or punch your own openings wherever your conduit runs land. That is the point of the NK version, it gives you a blank 16 gauge carbon steel shell to prep to your own layout. If you want factory knockouts, order a knockout version instead.
3) How does this B-Line enclosure mount to the wall?
Surface mount, using thru holes in the back of the box. You fasten straight through the rear panel into the wall or strut with your own hardware, so pick fasteners to suit the substrate. It is not a flush or recessed box.
4) Is this junction box UL listed for a commercial spec job?
The 444 SC NK is built to UL 50, the standard for enclosures for electrical equipment, and it is made in the USA. That plus the Type 1 rating is what most indoor commercial and institutional specs call for on a general purpose junction box.
5) What are the actual dimensions of the B-Line 444 SC NK box, and will a device or splice fit inside?
It is a 4 x 4 x 4 inch cube, 4 inches high, 4 inches wide, and 4 inches deep. That depth is generous for a box this size, so it suits conduit splices and small terminal work rather than being a shallow pull box. Weight is 1.9 lb.
6) Is the cover hinged or does it screw on?
Screw cover. The 444 SC NK uses a removable screw-on cover with plated screws and keyhole slots, so the cover lifts off after loosening rather than swinging open. The keyhole slots mean you can back the screws off and slide the cover free without fully removing them, which helps when you are on a ladder. If you need repeated access at a control point, a hinged-door enclosure is the easier choice.
7) How do I order the exact B-Line 4x4x4 screw cover no-knockout box?
Specify part number 444 SC NK from Eaton's B-Line series. The number reads as the size and the options: 4 x 4 x 4, SC for screw cover, NK for no knockout. Ordering 444 SC on its own gets you a knockout version, so keep the NK suffix if you want the blank box.
8) What color and finish is the B-Line 444 SC NK, and will it match our other electrical enclosures?
Painted ANSI 61 grey, the standard industrial enclosure grey used across most control and junction boxes, so it lines up visually with typical panel and disconnect finishes on the same wall.
