B-Line Eaton series Type 1 junction boxes, 10" height, 4" length, 10" width, 1, Screw cover, SC NK enclosure, Surface mounted, Small single door, No

No. The 10104 SC NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It gives no protection against rain, hose-down, or dust ingress. For a damp or outdoor location you need a NEMA 3R or 4/4X enclosure instead.

The box measures 10 inches high by 10 inches wide with a 4 inch depth. The 10 x 10 face gives you a square gutter area behind the cover, and the 4 inch depth is what determines conductor bending space, so size your conduit entries and splice count against that depth per NEC pull and junction box rules.

No knockouts. The NK in the model designation means no knockout, so the box ships with blank sides and back and you drill or punch your own entries where the conduit runs land. If you want factory conduit openings, order a knockout version instead of the NK.

It is a surface mount box with thru holes in the back pan, so it fastens flat to a wall, column, or backboard with your own screws or bolts, anchors sized to the substrate. At 6.4 lb empty, plus conduit and conductors, a 16 gauge carbon steel box wants anchors rated accordingly rather than drywall-only fasteners. The cover also has keyhole slots, so it can be hung and then secured without juggling all the screws at once.

A screw cover box like this one is the right choice where the box is a splice or pull point you rarely open. The cover comes off entirely, which gives you full access for pulling wire, and the screws hold it tight against tampering. Choose a hinged door enclosure instead when there is equipment inside you need to inspect or reset regularly, since a removable screw cover is awkward to handle overhead or in a tight space.

Order Eaton B-Line model 10104 SC NK. The number reads as the box dimensions followed by SC for screw cover and NK for no knockout, so a 10104 is 10 inches by 10 inches by 4 inches.

It is painted ANSI 61 grey, the standard light grey used across most industrial control and enclosure lines, so it will read the same as other ANSI 61 panels and gutters in the same room. The screws are plated.

Carbon steel, 16 gauge, painted. Being steel, the box bonds as part of the equipment grounding path and holds up to physical abuse better than a PVC box, but it is not corrosion resistant like stainless or fiberglass and should stay out of wet or chemical areas. Country of origin is the US.
