B-LINE 241810 RTSC NK – Frequently Asked Questions

1) Can the B-Line 241810 RTSC NK junction box be mounted outdoors?
Yes. The Eaton B-Line 241810 RTSC NK screw cover enclosure carries a NEMA Type 3R rating, so it is built for outdoor use against rain, sleet and snow. It ships with a rain hood over the door and plated screws on the cover. It is not a washdown or hosedown enclosure; for direct spray or dust-tight service you want a Type 4 or 4X box instead.
2) What are the box dimensions on the B-Line 241810 RTSC NK enclosure?
It measures 24 inches high, 18 inches wide and 10 inches deep, which is the 241810 in the model designation (height x width x depth). Plan for the rain hood projecting above the door and for cover screw clearance when you lay out the wall space.
3) Does this B-Line 3R enclosure come with knockouts, or do I have to drill my own conduit entries?
No knockouts. The NK in 241810 RTSC NK means the box ships blank, so every conduit entry is field-made in 16 gauge carbon steel. On a 3R box, put your entries in the bottom or the lower sides and use listed rain-tight hubs or fittings so you do not defeat the rating. If you would rather not drill, order a knockout version instead.
4) How does the B-Line 241810 RTSC NK mount to a wall?
Surface mount. The back has embossed thru holes, so you bolt or lag it flat against the wall or a strut rack. At 31.4 lb empty plus conductors and devices, anchor into studs, masonry or backing, not drywall alone.
5) Is the screw cover a hinged door, and how often can I get into this box?
The 241810 RTSC NK uses a flanged screw cover, styled as a medium single door. Every screw comes out to open it, so it suits a pull box or splice enclosure you rarely enter. If crews need daily access, a hinged latching 3R enclosure is the better choice.
6) Will this B-Line enclosure match the other grey panels on my site?
The finish is painted ANSI 61 grey, the standard gear grey used across most industrial panelboards and control enclosures, so it blends with existing switchgear and disconnects. The body is carbon steel, so keep the paint intact at field-drilled holes to avoid rust on an outdoor install.
7) Is 16 gauge steel heavy enough for a 24 x 18 outdoor pull box?
Yes for normal outdoor service. The 241810 RTSC NK uses 16 gauge carbon steel walls, which is the usual body thickness for a box this size and keeps the 24 x 18 x 10 shell rigid once it is bolted flat to a wall through the embossed thru holes.
