B-Line 2418 SCF Eaton series other enclosure accessories, NEMA 1, ANSI 61 gray painted, Used as wiring boxes, junction and pull boxes, Steel, Type 1 screw cover, Flush mount, 16 gauge

The 2418 SCF is a 24 x 18 nominal Type 1 screw cover enclosure. Its stated dimensions are 25.5 in height, 19.5 in width and 25.5 in length/depth, and it weighs 9.4 lb. Use those figures when you lay out wall space or check a rough opening, since the overall footprint runs larger than the nominal 24 x 18 designation.

No. NEMA 1 is indoor use only, for protection against incidental contact with the enclosed equipment and falling dirt. It is not rated against rain, hose-down, or dust-tight service. For an exterior wall, a loading dock, or anywhere subject to water, you need a NEMA 3R, 4, or 4X enclosure instead.

Yes, that is its intended use. Eaton lists it for wiring boxes, junction boxes and pull boxes, and it is UL Listed. The screw cover comes off completely so you can pull and train conductors through the box rather than working around a hinged door.

The F indicates a flush mount cover. On the 2418 SCF the cover sits within the enclosure rim rather than lapping over the outside edges, giving a flat face. If your spec calls for an overlapping (SC) cover that seats over the box flange, the flush version is not the same part and the cover will not interchange.

Screw cover boxes suit enclosures you rarely open, junction and pull points, splices, and terminal blocks where the cover comes off once at install and stays put. If someone will be opening the box regularly for resets, metering, or troubleshooting, a hinged or continuous-hinge cover is the better pick, because a 24 x 18 flush screw cover has to be fully unscrewed and handled off the wall each time.

Steel with an ANSI 61 gray painted finish, which is the standard gray Eaton uses across the B-Line enclosure line and the common finish on commercial switchgear and panel enclosures. If your existing boxes are ANSI 61 gray, this one will read as the same color on the wall.

The body is 16 gauge steel. At 24 x 18 that gauge holds its shape well enough to support field-punched conduit hubs and connectors on the sides and bottom without oil-canning, and the whole assembly weighs 9.4 lb, so a pair of anchors into studs or masonry handles it.

It ships as an unpunched NEMA 1 screw cover enclosure, so conduit openings are made in the field to suit your raceway layout. Plan on a knockout punch set sized to your conduit trade sizes plus the appropriate connectors or hubs, none of which are part of the box.
