B-LINE 444 SCGV NK – Frequently Asked Questions
1) Can the B-Line 444 SCGV NK junction box be used outdoors or in a damp location?
No. The 444 SCGV NK carries a NEMA Type 1 rating, which is indoor-only protection against incidental contact and falling dirt. It offers no protection against water, so keep it out of wet or washdown areas and off exterior walls. For outdoor work you need a Type 3R or better enclosure.
2) Does this 4x4x4 B-Line box come with knockouts for conduit?
It does not. The 444 SCGV NK is the no-knockout version, so every side and the back are solid galvanized steel. You drill or punch your own openings wherever the conduit runs land, which is why installers pick it for non-standard hole patterns. If you want factory knockouts, order a knockout version instead.
3) How is this junction box mounted, and is hardware included?
It is a surface mount box with thru holes in the back panel, so it fastens flat to a wall, stud, strut, or panel using your own screws or bolts sized to the substrate. Thru holes mean the fasteners pass through the enclosure interior, so allow for the screw heads when you lay out splices. There is no flush or recessed trim option with this box.
4) What are the actual inside dimensions and volume of the B-Line 444 junction box?
It's a 4 inch cube: 4 inch height, 4 inch width, and 4 inch length/depth. That's the standard 4-11/16 class of small pull and splice box footprint at a nominal 4x4x4, and it weighs 1.9 lb bare.
5) How does the cover attach on the B-Line SCGV screw cover box, and can it be removed for service?
The cover is a screw-on type with plated screws, and it has keyhole slots so you can back the screws off part way and lift the cover free without fully removing them. That matters on a ladder or in a ceiling space, where dropped screws are the usual problem. It is not a hinged door, so plan on two hands for service access.
6) Is the B-Line 444 SCGV NK UL listed for commercial and institutional electrical work?
Yes. It is built to UL 50, the standard for enclosures for electrical equipment, which is the listing most facility and institutional specs call for on a Type 1 junction box. Country of origin is the US.
7) What gauge steel is the B-Line 444 junction box, and will it hold up in a mechanical room or warehouse?
The body is 16 gauge galvanized steel, which is the heavier end for a small pull box and stands up to knocks in mechanical rooms, back-of-house corridors, and industrial spaces far better than a light sheet metal box. The galvanizing gives corrosion resistance in dry indoor environments; it is not a substitute for a rated outdoor enclosure.
8) Should I order the no-knockout box or one with knockouts for a standard conduit run?
Pick by how predictable your entries are. The 444 SCGV NK has no knockouts, so it suits jobs where conduit enters at odd locations, where you want the box sealed until you commit, or where the knockout pattern would never line up anyway. If your runs are standard trade size EMT entering at typical points, a knockout version saves field drilling time. Either way it is the same 4x4x4 screw cover Type 1 enclosure.
9) What is the exact part number to order this Eaton B-Line 4 inch screw cover box?
The catalog number is 444 SCGV NK from the Eaton B-Line series. The 444 is the 4 x 4 x 4 inch size, SCGV is the galvanized screw cover style, and NK designates no knockouts. Quote that full string, since the same size exists with knockouts under a different suffix.
