No. The 663 SC 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, dust, or oil. For an exterior wall, a loading dock, or a kitchen, you need a NEMA 3R, 4, or 4X enclosure instead. Inside a dry electrical room, corridor, or above a ceiling, the Type 1 box is the normal choice.

Yes, the box is knocked out on multiple faces: 3 knockouts on the sides, 3 on the top, and 3 on the bottom. That lets you run conduit straight through top to bottom or break out either side without drilling. The cover itself is not knocked out, so all entries come through the body.

It is built to UL 50, the standard for enclosures for electrical equipment, and rated NEMA Type 1. That is the pairing an inspector expects on an indoor surface mounted steel pull box. It is also made in the US, which matters on jobs with domestic sourcing requirements.

It is a surface mount box with thru holes in the back pan, so you fasten it flat to a wall, stud, or strut with your own screws, bolts, or toggles. Thru holes mean the fasteners pass into the box interior, so allow for the screw heads when you plan your wire routing. Anchors and screws are not part of the box; pick fasteners to suit the substrate.

It is a screw cover, not a hinged door. The cover lifts off entirely once the plated screws are backed out, and it has keyhole slots so you can loosen the screws and slide the cover off rather than removing them completely. That is quicker for a box you open occasionally, but if you are servicing it daily, a hinged cover enclosure is less hassle.

The body is carbon steel at 16 gauge, painted ANSI 61 grey. ANSI 61 is the standard grey used across most commercial panelboards, wireways, and control enclosures, so it lines up visually with existing gear in a typical electrical room. The paint is not a corrosion coating for wet or chemical areas; that is a stainless or non-metallic enclosure decision.

Order Eaton B-Line part number 663 SC. The number reads as the dimensions plus the cover style: 6 high, 6 wide, 3 deep, SC for screw cover. Anyone specifying a B-Line pull box will recognise that convention, which makes it easy to scale up or down within the same family.

The box weighs 2.7 pounds empty, so a single person can hold it in place while fastening. On hollow drywall it still needs proper anchors or a backing board once conductors and connectors add weight, but on strut or a stud it is a straightforward two-screw hang.
