B-Line Eaton series wireway elbow fitting, Lay-in, 90° elbow, outisde opening, 1, Steel, ANSI 61 gray painted finish, 10" X 10"

Yes. The Eaton B-Line 1010 FL OUT is sized for 10 inch by 10 inch lay-in wireway, with a stated product height of 10 inches and length/depth of 10 inches. It turns a run 90 degrees on the outside opening. If your trough is 4 x 4, 6 x 6 or 8 x 8, this is the wrong size fitting.

It comes down to which face of the turn the removable cover sits on. The 1010 FL OUT is the outside-opening version, so the cover is on the outer radius of the 90 degree turn, which is what you want when the inside corner of the elbow faces a wall or another piece of equipment and you need to lay conductors in from the open side. If the accessible side of your turn is the inner corner, you need the inside-opening elbow instead.

No. The 1010 FL OUT elbow is a NEMA 1 enclosure rating, which is indoor, general purpose protection against incidental contact and falling dirt only. For rooftop, washdown or damp areas you need a NEMA 3R or 4 rated wireway fitting instead.

It's a lay-in fitting, so the cover comes off and conductors drop straight into the trough at the turn. That's the reason to use a wireway elbow instead of a conduit ell: no pulling around the corner, and the bend is accessible afterward for re-work.

Steel with an ANSI 61 gray painted finish, the standard gray used across B-Line lay-in wireway and its fittings, so it matches adjacent trough and couplings on the same run.

Allow for a 14.41 inch overall width on the fitting, in addition to the 10 inch height and 10 inch depth. Tight corners against a column or panel can leave you short, so check the dimension before you cut the straight sections.

About 13.383 lb. Worth accounting for when you size trapeze or strut support at the corner, since the elbow plus the wire fill at the turn lands on the same hangers.
