B-LINE 16124 SCGV NK – Frequently Asked Questions
1) Can a NEMA 1 junction box like the B-Line 16124 SCGV NK be installed outdoors or in a wet area?
No. The 16124 SCGV NK carries a NEMA Type 1 rating, which is indoor use only and offers no protection against rain, washdown, dust or oil. For exterior walls, unheated loading docks, parking structures or anywhere hose-down or condensation is expected, you need a Type 3R, 4 or 4X enclosure instead. Indoors, dry, clean mechanical and electrical rooms are what this box is built for.
2) Does this B-Line screw cover box come with knockouts, or do I have to drill my own conduit entries?
No knockouts. The 16124 SCGV NK is the NK (no knockout) version, so every side and the back are blank steel and you punch your own openings where the conduit actually lands. That is what electricians normally want on a pull or splice box, but if you wanted factory holes on a fixed layout, order the knockout version of the same box instead.
3) How does this junction box mount to the wall?
Surface mount, using thru holes in the back of the box, so it fastens flat to block, drywall backing, plywood or Unistrut with your own anchors or screws (fasteners are not supplied). The box is not designed to be flush or recessed into a wall. At 10.4 lb empty it is a one-person hang, but pick anchors rated for the box plus conductors.
4) Is a screw cover or a hinged door better for a junction box I have to open often?
The 16124 SCGV NK uses a screw-on cover, which means removing several plated screws every time you get in. That is fine for a pull box, splice point or gutter you touch rarely, and it keeps the cover captive and tamper-resistant. If it is a box a tech opens weekly for testing or terminations, a hinged-cover enclosure will serve you better. One help here: the cover has keyhole slots, so you can back the screws out part way and lift the cover off without fully removing them.
5) What gauge steel is the B-Line 16124 SCGV NK, and will it rust in an unheated indoor space?
Body and cover are 16 gauge galvanized steel, left unfinished (grey mill finish, no paint). The zinc coating handles ordinary indoor humidity in a mechanical room, warehouse or basement, but galvanized steel is not a corrosion-resistant enclosure: keep it out of washdown, coastal exposure and chemical areas. If the box will be painted to match a finished space, prime for galvanized first.
6) Which exact B-Line part number do I order for the 16 x 12 x 4 screw cover box with no knockouts?
Order Eaton B-Line part 16124 SCGV NK. The number reads as its dimensions: 16 high, 12 wide, 4 deep, SC for screw cover, GV for galvanized, NK for no knockout. That is the single model on this product, so there is no finish or size option to specify.
