B-Line 3018 TCF Eaton series utility cabinets, NEMA 1, ANSI 61 gray painted, Protects against contact with enclosed equipment, Steel, Type 1 telephone termination cabinet, Flush mount, Utility cabinets, 12 gauge

No. The 3018 TCF is a NEMA 1 enclosure, which means indoor use only, protecting personnel against contact with the enclosed equipment. It offers no rated protection against rain, hose-down, dust or corrosive liquids, so a mechanical room, telecom closet or finished interior wall is the right place for it. For a wet or outdoor location you need a NEMA 3R or 4 rated enclosure instead.

The cabinet measures 25 x 25 x 14 inches (height, length/depth, and width as published), so frame the opening to those dimensions plus your trim allowance. It is a flush mount cabinet, meaning the box sits inside the wall cavity with the door trim finishing to the wall surface, so the stud bay and wall depth have to accept the box before the drywall goes on.

Flush mount. The 3018 TCF is built to recess into the wall, which is what most spec writers call for in corridors, tenant spaces and lobbies where a projecting box would be in the way. If your wall is masonry or already finished and you cannot cut a 25 inch deep-bay opening, you want a surface mount utility cabinet rather than this one.

It is a telephone termination cabinet: a steel enclosure that houses telephone and low-voltage termination hardware, blocks and cross-connect field inside a wall, keeping people from contacting the equipment inside. Property managers and contractors use them at tenant demarc points and in telecom closets where the termination has to be protected but reachable.

It is 12 gauge steel, which is heavy for a termination cabinet and a good deal stiffer than the 16 and 18 gauge boxes commonly used for light telecom work. At 16.8 pounds, it is still a one-person set into a framed opening. The 12 gauge body is the reason this one holds up in back-of-house corridors, loading areas and school hallways.

It comes painted ANSI 61 gray, the standard light gray used across most commercial electrical gear, so it will read as a match next to panels, wireways and pull boxes finished to the same standard. That is the practical reason to pick it when you are standardizing enclosure appearance across a facility.
