No. The 66120 G NK is a NEMA 1 wireway, which is indoor, general purpose only. It offers no protection against rain, dripping water, or hosedown, so keep it inside dry mechanical rooms, electrical rooms, and similar spaces. For a wet or outdoor location you need a NEMA 3R raintight wireway instead.

No knockouts. The 66120 G NK is supplied blank, so every conduit entry gets field drilled or punched where you want it. That's the version electricians usually prefer when the conduit layout isn't on a standard spacing, but it does mean budgeting time for a hole saw or knockout punch on the job.

It's a screw cover, not hinged. The cover is secured with plated screws along the length and lifts off completely once they're backed out. That gives full open access for laying in conductors, which is easier for an initial pull than a hinged cover, but it means loose hardware to keep track of on service calls. If you're opening the same run constantly for troubleshooting, a hinged cover style is friendlier.

16 gauge steel, finished in ANSI 61 gray. That's the standard gray that matches most panelboards, disconnects, and enclosures in a commercial electrical room, so a run of it blends with the rest of the gear rather than standing out. The 16 gauge body is what lets it take through-hole mounting and field-punched conduit entries without deforming.

Yes, it's CSA Certified, so it's acceptable for Canadian installations as well as US work. That matters on spec jobs where the submittal has to show a recognized certification mark on the raceway.

What ships is the 120 inch wireway body with its screw-on cover and plated screws. Couplers, end plates, elbows, tees, and any hanger or strut hardware are separate items, so lay out the run first and count the fittings before you order, otherwise the sticks land on site and the run can't be closed up.

Order it as B-Line 66120 G NK. The 66 is the 6 x 6 section, 120 is the length in inches, and NK means no knockouts. If your layout wants factory knockouts instead, that's a different suffix, so don't drop the NK when you quote it.
