B-Line Eaton series wireway cross fitting, Lay-in, Wireway cross fitting, 1, Steel, ANSI 61 gray painted finish, 10" X 10"

Yes. The Eaton B-Line 1010 HSX is sized for 10 inch by 10 inch wireway, with a 10 in height and 10 in width on the throat openings. It joins four runs at one intersection, so any trough branching off it also needs to be 10 x 10. Overall the fitting measures 21.5 in in its length/depth dimension, so allow that much clearance across the intersection when you lay out the run.

No. The 1010 HSX is a NEMA 1 enclosure type, which is indoor, general purpose protection against incidental contact with the enclosed wiring and falling dirt. It is not a raintight fitting. For an exterior run, a rooftop, or a washdown area you need a NEMA 3R or NEMA 4 wireway cross instead.

Lay-in means the cover comes off so conductors drop straight into the trough rather than being pulled through. At a four-way intersection that matters a lot: you can dress and land the cables in the cross with the cover open, then close it up. The 1010 HSX is a lay-in fitting, which is why it is the common choice for branch-off points on a field-installed run.

Steel with an ANSI 61 gray painted finish. ANSI 61 gray is the standard finish used across B-Line wireway trough and fittings, so the cross matches adjacent straight sections, elbows and tees in the same series without touch-up.

Use the cross only where four trough runs meet at one point. If the run continues straight and one branch leaves it, a tee is the correct fitting and takes up less space. The 1010 HSX is a four-way cross for 10 x 10 wireway; it occupies 21.5 in across, so on a tight ceiling a tee plus a short section is sometimes the better layout.

The 1010 HSX weighs 15.183 lb by itself. Add conductor weight and plan hangers at the intersection: a cross is a concentrated load point where four trough runs meet, so most installers support it independently rather than letting the adjoining sections carry it.
