B-LINE 4412 GRTGV NK – Frequently Asked Questions
1) What size is the B-Line 4412 GRTGV NK wiring trough?
The 4412 GRTGV NK is a 4 x 4 x 12 inch trough: 4 inch height, 4 inch width, 12 inch length. That is the standard 4 by 4 gutter cross section, so it lines up end to end with other 4 by 4 trough sections and fittings when you need a longer run.
2) Does the B-Line 4412 GRTGV NK come with knockouts?
No. The NK designation means no knockouts, so the trough ships blank and you punch conduit openings where your run actually lands. Bring a knockout punch set sized to your conduit, plus connectors and locknuts, since none are included.
3) Is the Eaton B-Line 4412 GRTGV NK trough approved for Canadian jobs?
It carries CSA C22.2 certification, which is the Canadian standard series for electrical enclosures. If your inspector wants CSA marking on the trough, this one has it.
4) What gauge steel is the B-Line 4412 trough and what finish is it?
16 gauge steel, finished gray. That is the usual body thickness for indoor gutter and trough work where the enclosure carries its own cover and mounting loads.
