No. The 884 SC NK is a NEMA Type 1 enclosure, which is indoor use only and offers no protection against rain, hose-down, or dust ingress. Use it in dry indoor locations such as electrical rooms, mechanical rooms, and finished interior walls. For wet or outdoor work you need a Type 3R or Type 4 enclosure instead.

It is 8 inches high, 8 inches wide, and 4 inches deep, so an 8x8x4 screw cover box. The 4 inch depth is the number that usually decides the job, since it sets how much room you have behind the cover for splices, wire nuts, and a bending radius on larger conductors.

It does not. NK means no knockouts, so the box ships blank and you punch your own openings wherever the conduit runs land. That is an advantage on a custom layout and extra labor if you expected pre-punched hubs. Plan on a knockout punch or hole saw sized to your connectors.

It carries UL 50, the standard covering enclosures for electrical equipment, and it is made in the US. That plus the NEMA Type 1 rating is what a spec or an inspector typically wants to see on an indoor junction box.

Surface mounting through thru holes in the back of the box, so it fastens flat against a wall, strut, or backboard with your own anchors or screws. Fasteners are not part of the box, so pick them for the substrate you are hitting. At 4.6 pounds empty it is a light box, but weight climbs once conduit and conductors are landed on it.

Screw cover, not hinged. The cover lifts off completely once the plated screws are backed out, and keyhole slots on the cover let you loosen the screws rather than fully remove them to pull the cover. For an enclosure you open often, a hinged door style is the easier choice; for a box you splice once and close, the screw cover is the normal spec.

16 gauge carbon steel with a painted finish in ANSI 61 grey, the standard gear grey that matches most panelboards and industrial control enclosures. The 16 gauge body holds its shape when you punch knockouts and lands hardware without oil canning.

884 SC NK is the Eaton B-Line catalog number. The digits read as the dimensions, 8 high by 8 wide by 4 deep, SC for screw cover, NK for no knockouts.

For indoor pull boxes, splice points, and small terminal blocks it is a reasonable standard: one size at 8x8x4, one color in ANSI 61 grey, and no knockouts so every box gets punched for whatever conduit arrives at it. Where a run leaves the building or enters a wet area, you will have to break from it and spec a rain tight or watertight type, since this one is Type 1 only.
