B-LINE 1266 SC NK – Frequently Asked Questions

1) Can the Eaton B-Line 1266 SC NK junction box be used outdoors or in a wet location?
No. The 1266 SC NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact with the enclosed equipment and falling dirt. It offers no protection against rain, splashing water, hose-down, or dust ingress. For an outdoor or washdown location you need a Type 3R, 4, or 4X enclosure instead.
2) What are the actual box dimensions of the B-Line 1266 SC NK enclosure?
It measures 12 inches high, 6 inches wide, and 6 inches deep. That 6 inch depth is what usually decides the job, since it sets how much room you have behind the cover for splices, terminal blocks, or a small din rail. Shipping weight is 6.4 lb.
3) Does this B-Line junction box come with knockouts for conduit?
No knockouts. The 1266 SC NK is a blank box, so every conduit entry has to be punched or hole-sawed on site wherever your run lands. That is the point of the NK version: you place the openings yourself. If you want factory openings, order a knockout version of the same box instead.
4) How does the cover come off on the 1266 SC NK, and is it hinged?
It is a screw cover, not a hinged door. The cover lifts off entirely once the plated screws are backed out, and it has keyhole slots so you can loosen the screws rather than remove them completely and still drop the cover free. Good for a box you open rarely; if you need frequent access, a hinged-door enclosure is the better pick.
5) How does this junction box mount to the wall?
Surface mount, using thru holes in the back of the box. You fasten straight through the back pan into the wall or strut, which means the fasteners are visible inside the enclosure and you need to keep them clear of your wiring. Mounting hardware is not part of the box, so pick anchors to suit the substrate.
6) What gauge steel is the B-Line 1266 SC NK made of and how is it finished?
16 gauge carbon steel, painted ANSI 61 gray. That is the standard gray used across most commercial electrical gear, so it matches typical panelboards and control enclosures in the same room. The steel body also means you can punch it in the field for connectors and that the enclosure itself is part of the bonded metal system.
7) What part number do I order for the 12 x 6 x 6 B-Line screw cover box with no knockouts?
The catalog number is 1266 SC NK from Eaton's B-Line series. The digits read as the dimensions, 12 high by 6 wide by 6 deep, SC for screw cover, NK for no knockouts.
8) Is the Eaton B-Line 1266 SC NK made in the USA?
Country of origin is the United States, which matters if you are procuring for a government, institutional, or federally funded project with domestic sourcing language in the spec.
