B-LINE 644 SCGV NK – Frequently Asked Questions

1) Can the Eaton B-Line 644 SCGV NK junction box be used outdoors or in a wet location?
No. The 644 SCGV NK is a NEMA Type 1 enclosure, which is indoor-only protection against incidental contact and falling dirt. It has no gasket and no wet-location rating, so damp, washdown, or outdoor mounting calls for a NEMA 3R or 4X box instead.
2) What are the actual box dimensions on the B-Line 644 junction box?
It measures 6 inches high, 4 inches wide and 4 inches deep. That is the usable pull-box envelope, so size your conduit entries and bending space against a 4 by 4 inch cross section.
3) Does this B-Line junction box come with knockouts for conduit?
No knockouts. The 644 SCGV NK ships blank, so the installer drills or punches every conduit entry where it suits the run. If you want factory holes, order a box specified with knockouts rather than the NK version.
4) Is the B-Line 644 SCGV NK UL listed for an inspected commercial job?
Yes, it is built to UL 50, the standard for enclosures for electrical equipment, and made in the US. Pair that with the Type 1 rating when you list it on a submittal for an indoor dry location.
5) How does this enclosure mount to a wall, and are mounting holes provided?
Surface mount, with thru holes in the back of the box for screws or bolts into the wall. The cover also has keyhole slots, so it can be lifted off the plated cover screws without fully backing them out. Fasteners for the wall itself are not supplied.
6) Is the cover on the B-Line 644 SCGV hinged or screw-on?
Screw cover, not hinged. That suits a pull or splice point you rarely open. For a box you will be getting into regularly, a hinged single-door enclosure is the easier choice.
7) What is the steel gauge and finish on this B-Line junction box, and will it rust in an unheated space?
16 gauge galvanized steel, left unfinished in a grey appearance. The galvanizing gives it better corrosion resistance in dry, unheated indoor areas like mechanical rooms and warehouses than painted plain steel, but it is still a Type 1 box and not for wet or corrosive environments.
8) What is the exact part number to order this 6x4x4 B-Line screw cover box?
Order Eaton B-Line model 644 SCGV NK. The number reads out as the dimensions (6 by 4 by 4), SC for screw cover, GV for galvanized, NK for no knockouts.
9) How heavy is this junction box for overhead or drywall mounting?
2.4 lb empty. Light enough to hang from toggle or self-drilling anchors in drywall, though anchor selection should account for the conductors and any device weight you add inside.
