No. The 6618 G trough is a NEMA 1 enclosure, which is indoor, general purpose only. It offers no protection against rain, dripping water, or washdown, so keep it inside dry areas. For a rooftop, exterior wall, or washdown area you need a NEMA 3R or 4 rated trough instead.

It is a 6 x 6 inch cross section running 18 inches long, so it gives you a square 6 by 6 raceway body. That cross section is what governs your wire fill and bend radius at the knockouts, and the 18 inch length is the run you get per section before you couple to the next one.

The cover is a screw cover held on with plated screws, so you back the screws out to open the trough and reinstall them to close it. That means full access along the whole 18 inch length for pulling and dressing conductors after the body is mounted, but it is a tool-required cover, not a hinged or quick-latch design. If you expect frequent access, plan for the screw time.

Yes, it ships with 5 knockouts on the top and 5 on the bottom, so you can feed conduit in and out without drilling the body. There are no factory knockouts called out on the ends or sides, so side entries would have to be field punched.

The 6618 G trough is CSA Certified. Confirm with your AHJ which listing marks they accept for wireway on your project.

The body is 16 gauge steel finished in ANSI 61 gray, the standard gray used on most industrial panelboards and control enclosures, so it matches gear already on the wall. The screws are plated.
