No. The 664 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, washdown, dust, or corrosive environments. For an exterior wall, a loading dock, or a wet mechanical room you need a NEMA 3R or NEMA 4 enclosure instead.

It ships with no knockouts. The SC NK box is a blank carbon steel enclosure, so every conduit entry gets punched or drilled on the job to suit your raceway layout. That is the point of the NK version: you place the holes where the run actually lands. Plan on a knockout punch set and the right connectors or hubs for your conduit type, since none are included.

The 664 measures 6 inches high, 6 inches wide, and 4 inches deep. That 4 inch depth is what matters most for wire bending room, so it handles a straightforward splice or a small pull point comfortably, but it is not a gutter or a device box. Check your conductor count and size against box fill rules before committing.

Yes, it is built to UL 50, the standard covering enclosures for electrical equipment. That plus the NEMA Type 1 rating is typically what an inspector or a facility spec is looking for on an indoor junction box.

It is a surface mount box with thru holes in the back for fastening straight to a wall, panel, or strut. The anchors or screws are not part of the box, so pick fasteners to suit the substrate: toggles or self-drilling anchors for drywall, sleeve anchors for masonry. The enclosure weighs 3.1 lb empty, so the fastening only has to carry the box plus whatever conductors land in it.

Screw cover, not hinged. The cover lifts off entirely once the plated screws are backed out, and it has keyhole slots so it hangs on the loosened screws while you work rather than dropping. Good for a junction or pull point you rarely open. If the box needs opening routinely for service, a hinged door enclosure is the better choice.

The body is 16 gauge carbon steel, painted ANSI 61 grey. That is a standard industrial enclosure wall thickness, stiff enough for a mechanical room, shop, or plant wall where it may take a knock. The painted carbon steel finish is for dry indoor use; it is not stainless and is not intended for corrosive or washdown areas.

Most likely yes. It is finished in ANSI 61 grey, the standard enclosure and control panel grey used across industrial gear, so it blends with existing panels and pull boxes from the same family. For standardizing a facility, the full model designation to specify is 664 SC NK.

Country of origin is the United States. That matters on public and institutional work where domestic sourcing is a condition of the contract.
