The 4412 G is a 4 x 4 inch cross section, 12 inches long. That 4 by 4 trough is the standard size for feeder and branch circuit gutters where conductors need room to turn into panels or disconnects. Height is listed at 4 in, width at 4 in, and length at 12 in, so it drops into a short run between two enclosures without cutting.

No. The 4412 G is a NEMA 1 enclosure, which is indoor, dry location only. It gives protection against incidental contact with the enclosed wiring and falling dirt, but nothing against rain, washdown, or dust ingress. For an exterior wall, a rooftop, or a wash bay you need a NEMA 3R or NEMA 4 raintight wireway instead, which uses a gasketed cover rather than a plain screw cover.

Knockouts are already there: three on the top and three on the bottom of the 4412 G. So a straight-through feed with conduit entering below and leaving above is ready without a hole saw or a knockout punch. Anything beyond those six locations, including end or side entries, you cut yourself.

It is a screw cover. The cover is secured to the body with plated screws, so you back the screws out to open the full length of the trough for laying in conductors, then reinstall them. That is slower on a long run than a hinged or slip-on cover, but it is the common spec for gutters that get opened rarely after the initial pull. Plated screws resist corrosion in normal indoor service.

The body is 16 gauge steel finished in ANSI 61 gray, the same standard gray used on most commercial panelboards, disconnects, and control enclosures, so a run against existing gear generally matches without repainting. Sixteen gauge is the usual weight for a screw cover gutter of this size and holds its shape when the cover is off during a pull.

Yes, within the 4 x 4 family. Wireway is built to be coupled end to end, and any section, elbow, or fitting sized 4 x 4 lines up with this one. The 12 inch length is the short section used for filling out a run or bridging two closely spaced enclosures. Longer straight lengths and the connectors, elbows, and end caps needed to close out the run are ordered separately.

No. What you get is the 12 inch trough with its screw cover and plated screws. End plates to close the run, couplers to tie sections together, elbows, hangers, and conduit fittings for the knockouts are all separate line items. Count them before the order goes out so the gutter is not sitting open on site.

Order it as B-Line 4412 G. The number reads the same way the rest of the family does: a 4 x 4 inch trough, 12 inches long, G type screw cover wireway in NEMA 1.
