B-Line Eaton series wireway elbow fitting, Lay-in, 90° elbow, outisde opening, 1 rated, Steel, ANSI 61 gray painted, 4" X 4"

No. The 44 FL OUT is NEMA Type 1 only, which is indoor, dry location use against incidental contact with falling dirt. For a rooftop, a wash-down area, or anywhere weather or liquid reaches the trough, you need a Type 3R or Type 4 wireway fitting instead. Mixing a Type 1 elbow into an otherwise raintight run downgrades the whole run at that point.

On the 44 FL OUT, the removable cover and the lay-in opening are on the outside of the turn, the long radius face. Stand where the run changes direction: if you need to drop conductors in from the outer corner of the bend, this is the fitting. If your access is on the inner corner, you want the inside-opening version instead. Getting this backwards leaves the cover facing a wall and no way to lay wire in.

Order it as Eaton B-Line 44 FL OUT. The 44 is the 4 inch by 4 inch trough size, FL is the flat 90 degree elbow, and OUT designates the outside opening. The companion inside-opening fitting carries a different suffix, so give the full designation to your distributor rather than just asking for a 4x4 elbow.

Painted steel in ANSI 61 gray, the standard gray used across Eaton B-Line wireway and most industrial control gear. Set next to B-Line 4x4 lay-in trough and other ANSI 61 fittings it reads as one continuous run, so a facilities crew standardizing on gray wireway can add this elbow without a color mismatch at the corner.

It weighs 3.694 lb, so it is a one-hand fitting on a ladder. The wider face measures 8.366 inches across, which is the span you need to clear when you are planning a corner against a beam, a column, or an adjacent conduit rack.
