B-LINE 64120 G NK – Frequently Asked Questions

1) Is the 64120 G NK wireway rated for outdoor or wet locations?
No. It is a NEMA 1 enclosure, which is indoor, dry-location only. The cover is fastened with plated screws and there is no gasket, so rain, washdown, or dripping oil will get in. For an outdoor run or a washdown area you need a NEMA 3R or NEMA 4 raintight wireway instead.
2) Does this B-Line wireway come with knockouts for conduit, or do I have to punch my own?
This is the NK (no knockouts) version, so the sides and ends come solid. You drill or punch your own openings wherever the conduit lands, which is what most installers want on a field-routed run. If you would rather have factory holes on a set pattern, you need the knockout version of the same size, not this one.
3) Will a 16 gauge screw-cover wireway hold up in an industrial plant?
The body is 16 gauge steel with a screw-on cover, which is the standard commercial and industrial construction for NEMA 1 wireway. Screw covers sit tighter than hinged covers and are the right pick where the run is set once and rarely opened. If your electricians will be in and out of the trough constantly, a hinged-cover wireway saves labor.
4) Is this wireway certified for use in Canada?
Yes, the 64120 G NK is CSA Certified, so it can be used on Canadian projects as well as US work. The cited certification is CSA; nothing else is claimed for it.
5) What part number do I order for the 4 x 6 x 120 inch B-Line no-knockout wireway?
Order Eaton B-Line 64120 G NK. The number reads out as the size: 6 inch height, 4 inch width, 120 inch length, G series, NK for no knockouts.
6) Do I need anything besides the wireway sticks to complete the run?
The trough ships as a 120 inch section with its screw cover. Connectors, end plates, elbows, tees, and hangers are separate items, and because this is the no-knockout version you also supply your own conduit hubs or connectors and punch the openings. Mounting bolts for the thru holes are not part of the trough either.
7) Will this gray wireway match the panels and existing trough already on my wall?
The finish is ANSI 61 gray, the standard industrial gray used on most switchgear, panelboards, and control enclosures, so it will read as a match alongside existing ANSI 61 equipment. Cover screws are plated rather than painted.
