B-LINE 121236 GGV NK – Frequently Asked Questions
1) Can I use the 121236 GGV NK wireway outdoors or in a washdown area?
No. The 121236 GGV NK is a NEMA 1 trough, which is general purpose indoor only. It gives you no protection against falling water, hose down, dust or corrosive atmosphere. For an exterior wall, a wet process area or a wash bay you need a NEMA 3R or NEMA 4/4X wireway instead.
2) Does this wireway come with knockouts for conduit, or do I have to punch my own?
No knockouts. The NK in 121236 GGV NK means the sides, ends and bottom come blank, so every conduit entry gets field punched exactly where you want it. That's the version most electricians prefer for a custom pull section, but if you'd rather have factory knockouts on a standard pattern, order the knockout version of the same size rather than this one.
3) How does the cover come off on the B-Line 121236 GGV NK wireway?
Screw cover. The lid is held on with plated screws all around the flange, so pulling the cover means backing out every screw, and you get a cover that stays put and won't rattle loose from vibration. If you're pulling wire in and out of the same trough repeatedly, a hinged cover wireway will save you time; if it's a one-time install that then gets left alone, the screw cover is the right choice.
4) Is the B-Line 121236 GGV NK wireway galvanized or painted?
Galvanized steel body in a gray finish, formed from 14 gauge material, with plated screws on the cover. The 14 gauge is heavier wall than the light duty troughs you see in residential work, which is what keeps a 12 x 12 section from oil canning when it's loaded with conductors.
5) I need a longer run than 36 inches of wireway. Can I join sections together?
Yes, wireway is built to be run in sections. The 121236 GGV NK is a 36 inch length of 12 x 12 trough, and you extend the run by ordering additional sections in the same 12 x 12 size and joining them with connectors. Keep the height and width identical across the run so the flanges and covers line up. Elbows, tees and end plates in 12 x 12 handle the direction changes and terminations.
6) What part number do I order for a 12 x 12 x 36 inch B-Line screw cover wireway with no knockouts?
The Eaton B-Line part number is 121236 GGV NK. The digits read as the dimensions, 12 inch height by 12 inch width by 36 inch length, GGV is the screw cover galvanized gutter series, and NK means no knockouts.
