B-LINE 4436 GRT NK – Frequently Asked Questions

1) Is the B-Line 4436 GRT NK wiring trough rated for outdoor or washdown use?
The 4436 GRT NK trough is built to NEMA 4X, so it is intended for wet, washdown, and corrosive-duty locations rather than dry indoor use only. It is also CSA Certified. The cover seals by a flange held down with plated screws, which is what keeps water out, so every screw has to go back in on reassembly for the 4X rating to mean anything in the field.
2) What size is the 4436 wiring trough and how much wire fill will a 4x4 gutter take?
It is a 4 inch by 4 inch cross section, 36 inches long. The 4x4 body is the most common gutter size for feeding panels and junctioning branch circuits, and the interior is clear because there are no knockouts punched in it. Weight is about 11.181 lb, so a single installer can hang it on standard strut or unistrut without help.
3) Does the 4436 GRT NK trough come with knockouts, or do I have to punch my own holes?
No knockouts. The NK in the model number means the body ships blank, so you punch or hole-saw exactly where your conduit runs land. That is the usual choice on a NEMA 4X gutter, since every unused knockout is a leak path you would have to seal. Plan on bringing a punch set and watertight hub fittings to the job.
4) How does the B-Line 4436 wiring trough mount to a wall?
Through embossed thru holes in the back of the enclosure, so you fasten straight to the wall, backboard, or strut with your own hardware. The embossed holes keep the mounting fasteners from breaking the sealing plane the way a drilled-on-site hole would. Mounting hardware and anchors are not part of the trough, so pull those separately.
5) Is the screw-cover style trough or a hinged cover better for a gutter I open often?
The 4436 GRT NK uses a screw cover, with plated screws around a flange. That is the right pick where the gutter is opened rarely and the seal matters, such as a 4X washdown or outdoor run. If you are pulling and re-terminating regularly, a hinged or quick-release cover saves time, because on a screw cover every fastener has to come out and go back in to keep the enclosure rating.
6) Can I join several 4436 troughs together for a longer run?
Yes, gutters like this are made to be coupled end to end into whatever length the run needs, with each 36 inch section adding to the pull. The bodies ship without knockouts, so you cut the connecting openings yourself at the joint. Note that any field-cut opening between sections has to be closed with fittings suited to a NEMA 4X installation if you want to keep the wet-location rating.
7) What exact part number should I order for the 4 by 4 by 36 inch B-Line screw cover gutter?
Order Eaton B-Line part 4436 GRT NK. The digits read as the cross section and length: 4 inch by 4 inch body, 36 inches long, GRT for the gutter series, NK for no knockouts.
