No. The 6418 G NK is a NEMA 1 enclosure, which means general purpose indoor use only, with no protection against rain, splashing water, or washdown. Run it in dry indoor areas such as mechanical rooms, electrical rooms, and manufacturing floors. For an outdoor feeder or a wet area, you need a NEMA 3R raintight wireway instead, not this one.

There are no factory knockouts. The NK in the model designation means no knockouts, so every conduit entry gets field punched or drilled where you want it. That is the usual choice for a laid-out feeder run where you control the entry points. If you'd rather have pre-punched holes to save field labor, order a knockout version of the same wireway family instead.

Yes. A wireway section like the 18 in 6418 G NK is the straight body only. Connectors between sections, end plates to close off the run, and any elbows or tees for direction changes are separate items, as are your mounting fasteners since the section uses thru holes. Since there are no knockouts, conduit entries are field punched too, so bring a punch set to the install.

The cover is a screw cover secured with plated screws, so access means backing the screws out rather than flipping a hinged lid. Fine for a pull section or a run you seldom open; if you are pulling and re-pulling conductors regularly, a hinged cover wireway saves a lot of time on the ladder.

It mounts with thru holes, meaning you fasten through the wireway body into your structure, strut, or backpan with your own hardware. No mounting feet or brackets are part of the wireway, so plan fasteners and any strut for the surface you're landing it on. At a listed 6.097 lb per section, a single 18 inch piece is a one-hand set for a single installer.

The section is listed at 6 in height, 18 in length, and 4 in width. Use the cross section, not the length, when you check your conductor fill and your bend radius at pull points, and use the 18 in length to work out how many sections plus connectors your run needs end to end.

It is CSA Certified, which is the listing a Canadian inspector looks for. Keep in mind it is a NEMA 1 general purpose enclosure, so the location it goes in has to be a dry indoor one for that certification to mean anything on your job.

Steel, 16 gauge, finished in ANSI 61 gray. That gauge and the gray finish are the standard commercial/industrial combination, so a section dropped into an existing run of ANSI 61 gray gear and wireway will match the rest of the installation rather than standing out.
