No. The 2248 G is a NEMA 1 enclosure, which is indoor, general-purpose only. It offers no protection against rain, dripping water, or washdown. For an outdoor run or a damp mechanical room you need a NEMA 3R raintight wireway instead. The 2248 G is CSA Certified.

It comes punched: 15 knockouts on the top and 15 on the bottom of the 48 inch section, so you can land conduit at regular intervals along the run without drilling. Nothing is punched in the ends, which is normal, ends are where sections couple or where you add a fitting.

It's a screw cover. The lid is secured with plated screws along its length, so you back the screws out to open the trough and reinstall them to close it. That is more time per access than a hinged or quick-latch cover, so if you are building a pull box you will be opening repeatedly, plan on the screw time or choose a hinged-cover trough.

Mounting is by thru holes in the trough back, so you fasten it directly to the wall, backboard, or strut with your own hardware. Fasteners and anchors are not part of the trough, so pick them for your substrate. At 8.547 lb per 48 inch section it is light enough for a two-point wall mount on solid backing.

Yes, that is the normal use for a screw-cover G series trough: an indoor NEMA 1 gutter for splicing and routing conductors between panels, with the 15 top and 15 bottom knockouts giving you conduit entry points. Just size it for fill, the 2-1/2 by 2-1/2 inch cross section is tight for large feeders, and the screw cover means every future splice is a screw-by-screw open.

16 gauge steel, finished in ANSI 61 gray, with plated screws on the cover. ANSI 61 gray is the standard gray used on switchgear and panelboards, so it matches most existing electrical equipment in a commercial room without repainting.
