B-LINE 12128 SCGV NK – Frequently Asked Questions

1) Can a B-Line 12128 SCGV NK junction box be used outdoors or in a washdown area?
No. The 12128 SCGV NK is a NEMA Type 1 enclosure, which is indoor use only and offers no protection against rain, splashing water, or hose-down. For an exterior wall, a rooftop, a parking garage, or a kitchen, you need a Type 3R or Type 4 enclosure instead. Indoors in a dry electrical room, riser, or above a ceiling, Type 1 is the normal choice.
2) What are the actual box dimensions of the B-Line 12128 screw cover junction box?
It is 12 inches high, 12 inches wide, and 8 inches deep, which is where the 12128 designation comes from. That 8 inch depth is generous for a box this size and is what gives you room to make up large conductors or land splices without cramming the wires. Weight is 11.6 lb, so one person can hang it.
3) Does the B-Line 12128 SCGV NK come with knockouts for conduit?
No knockouts. The NK in the part number means no knockout, so the box ships blank and you punch or drill your own conduit entries exactly where the run needs them. Budget time for a hole punch or a step bit on 16 gauge galvanized steel. If you would rather have factory openings, order a knockout version of the screw cover box instead.
4) How does this junction box mount to a wall or to strut?
It is a surface mount box with thru holes in the back pan, so you fasten it flat against the wall, plywood backing, or unistrut with your own hardware. Mounting screws or anchors are not part of the box. The cover also has keyhole slots, which lets you get the cover screws started and hang it while you line the rest up single handed.
5) Is the cover on this B-Line box hinged or does it screw on?
Screw cover. The cover comes off completely with plated screws rather than swinging on a hinge, which suits a pull box or splice box that is opened rarely. If your inspector or your electricians need frequent access and a cover that cannot be dropped or lost, specify a hinged cover enclosure instead.
6) Is this junction box UL listed for a commercial job?
Yes, the 12128 SCGV NK carries UL 50, the standard covering enclosures for electrical equipment, and it is built to NEMA Type 1. That combination is what specifiers normally call for on indoor pull and junction boxes in commercial work. It is made in the US.
7) What is the exact part number to order this Eaton B-Line screw cover box?
Order it as 12128 SCGV NK. Read the number as the box size and build: 12 inch height, 12 inch width, 8 inch depth, screw cover galvanized, no knockout. It is the only configuration under that number, so there are no finish or size options to select.
8) How heavy a gauge is the steel on this 12x12x8 junction box?
16 gauge galvanized steel through the body. That is the usual weight for a box this size and it keeps the walls stiff enough to hold a conduit hub or a punched entry without oil canning, and stiff enough to carry the 11.6 lb assembly plus conductors off a wall.
