B-LINE 16126 RTSC NK – Frequently Asked Questions

1) What are the actual box dimensions on the B-Line 16126 RTSC NK junction box?
It measures 16 inches high, 12 inches wide and 6 inches deep. The 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. Weight is 12.3 lb.
2) Does the 16126 RTSC NK box come with knockouts for conduit?
No. The NK in the model designation means no knockouts, so the box ships with blank walls and you punch your own conduit entries where the job needs them. For a 3R installation, make your entries in the bottom or the lower sides and use rain tight fittings so the enclosure keeps its rating.
3) Is the Eaton B-Line 16126 RTSC NK UL listed for an inspected commercial job?
It carries UL 50, the standard covering enclosures for electrical equipment. Paired with the NEMA 3R rating, that is what an inspector looks for on an outdoor junction or pull box. The enclosure is made in the US, which matters on projects with domestic sourcing requirements.
4) What is the 16126 RTSC NK enclosure made of, and will it hold up outdoors?
Carbon steel at 16 gauge, painted ANSI 61 grey. That is a substantial wall thickness for a box this size and it takes conduit hubs and device mounting without flexing. The paint plus plated cover screws handle normal outdoor exposure, but in coastal or corrosive chemical environments a stainless or fiberglass enclosure is the better call.
5) How does this B-Line screw cover box attach to a wall?
It is a surface mount enclosure with embossed thru holes in the back wall, so it bolts flat to a wall, a strut rack or a backboard using your own fasteners. The embossed holes keep the mounting hardware off the interior surface. It is not designed for flush or recessed mounting in a finished wall.
6) Is a screw cover box like the 16126 RTSC NK the right choice, or should I use a hinged door enclosure?
A screw cover box is for connections you rarely need to get back into: splices, taps, pull points, junction work. The flanged cover comes off completely with plated screws, which is fine on a once-a-year access but awkward on a ladder. If someone will be opening it regularly to reset a device or land field wiring, pick a hinged door enclosure instead so the cover stays captive.
7) What part number do I order for the 16x12x6 B-Line 3R screw cover box?
Order Eaton B-Line part number 16126 RTSC NK. The number reads straight off the size: 16 inch height, 12 inch width, 6 inch depth, RTSC for the rain tight screw cover style, NK for no knockouts.
8) Will a 16 x 12 x 6 junction box be big enough for my pull box calculation?
The 16126 RTSC NK gives you 16 inches in the long dimension, 12 across and a 6 inch depth. For straight pulls the box length has to be at least eight times the largest raceway trade size, and for angle or U pulls at least six times. Run your conduit sizes against those figures before committing, because the 6 inch depth is the tightest dimension here.
