B-Line Eaton series Type 1 junction boxes, 36" height, 12" length, 36" width, 1, Screw cover, SC NK enclosure, Surface mounted, Medium single door, N

No. The Eaton B-Line 363612 SC NK is a NEMA Type 1 enclosure, which is indoor only and gives no protection against falling water, dust ingress, hosedown or corrosive atmospheres. For a wet or outdoor location you need a Type 3R, 4 or 4X enclosure instead. This one is intended for clean, dry indoor electrical rooms and mechanical spaces.

36 inches high, 36 inches wide and 12 inches deep. That 12 inch depth is what usually decides the job, since it sets how much room you have behind the cover for wire bending space, terminal blocks or gutter taps.

No knockouts. The 363612 SC NK is supplied blank (NK stands for no knockout), so the installer punches or hole-saws every conduit entry where the run actually lands. Plan on a knockout punch set on site. The upside is you are not fighting factory openings that do not match your conduit layout.

113.7 lb empty, before any conduit, wire or terminal hardware. It mounts surface-style through thru holes in the back, so the fasteners and the wall have to carry that load plus the conduit runs. On stud walls that means hitting structure or adding backing or Unistrut; on block or concrete, use appropriately rated anchors. Two people for the lift is realistic.

It is a screw cover with plated screws, and the cover has keyhole slots so it hangs on partially backed-out screws while you line it up. That helps when a single electrician is handling a 36 by 36 inch steel lid overhead. If you need frequent access without removing hardware, a hinged door enclosure is the better choice; a screw cover is meant for infrequent entry.

Carbon steel at 12 gauge wall thickness, which is a heavy body for a junction box of this size and resists denting in a plant or shop environment. It is painted ANSI 61 grey, the standard gear grey that matches most switchboards and control panels. The limit is environmental, not mechanical: it is a Type 1 box, so keep it out of wet or corrosive areas.

It is built to UL 50, the standard covering enclosures for electrical equipment, and carries a NEMA Type 1 rating. That is the pairing a spec writer or facility engineer normally asks for on an indoor pull or junction box. It is also made in the US, which matters on Buy American and domestic-preference procurement.

Order Eaton B-Line part 363612 SC NK. The number reads as the dimensions first (36 high, 36 wide, 12 deep), then SC for screw cover and NK for no knockouts. If your drawing calls for factory knockouts or a hinged door instead, that is a different catalog suffix, so match the suffix and not just the size.
