B-Line Eaton series wireway, 4" height, 36" length, 4" width, GGV NK wireway, Thru holes, No knockouts, Screw cover, 4X, Galvanized steel, Plated scr

The 4436 GGV NK wireway is a NEMA 4X enclosure, so it handles hosedown, washdown, and wet or corrosive locations as well as indoor runs. It is built from galvanized steel in a gray finish and is CSA Certified. NEMA 4X is what you want for food processing, car washes, parking structures, and exterior walls where a standard NEMA 1 screw-cover trough would not hold up.

It is a 4 inch by 4 inch cross section in a 36 inch length, which is the standard commercial trough size for feeder taps and control wiring pulls. The 4 x 4 x 36 designation is where the model number comes from. Weight is 9.936 lb per section, so a single installer can hang it.

No knockouts. The 4436 GGV NK is the NK (no knockouts) version, so the sides and ends come solid and you punch or drill your own conduit entries where the run actually needs them. If you want factory knockouts on a set spacing, you need a knockout version of the wireway instead, not this one.

Each 4436 GGV NK is a single 36 inch straight section. Running longer than 36 inches, or turning a corner, means adding couplings, elbows, tees, or end plates from the same 4 x 4 GGV series so the NEMA 4X gasketing carries through the joint. Those fittings order separately from the trough section.

It is a screw cover, held on with plated screws along the length. You can remove the whole cover for pulling and re-splicing, but plan on backing out every screw each time, unlike a hinged or quick-latch cover. For a junction point you open often, a hinged-cover trough saves labor; for a sealed NEMA 4X run, the screwed cover is what maintains the rating.

Mounting is by thru holes in the trough body, so you fasten it directly to the wall, to unistrut, or to a backpan with your own hardware. Fasteners and any strut or brackets are separate items, not supplied with the wireway section.

Yes. The wireway is CSA Certified, so it is acceptable for work inspected to Canadian Electrical Code as well as US installations.

Galvanized steel with a gray finish and a 4X rating covers most damp, outdoor, and washdown environments, including exterior building walls and parking decks. Where the exposure is chemical, chlorinated, or coastal salt, spec a stainless trough instead. The 4X rating on this one speaks to water and general corrosion resistance, and the material is galvanized steel, not stainless.

The body is 16 gauge galvanized steel. That is the normal commercial wall thickness for 4 x 4 trough. On horizontal runs, support at the joints between 36 inch sections and the trough carries fine; the mounting is through-hole so you set the support spacing yourself.
