B-Line Eaton series imperial cable tray and ladder, 6" Height, 39.000" Length, 6" Width, Series 2-5 vertical outside bend, Aluminum, 90° Angle, 36" Ra

It's a 90 degree vertical outside fitting for a B-Line Series 2-5 aluminum cable tray run, used where the tray has to turn down over an obstruction or drop off a wall or ceiling line. Outside means the cable rides on the outside of the bend, so the tray turns away from the cable bundle. It's built on a 36 inch radius, which keeps the cable bend well above the tight-turn territory that damages large conductors. For a turn the other direction you need the vertical inside version, not this one.

Lay it out at 39 inches of overall length. That is the fitting's stated length dimension, driven by the 36 inch bend radius plus the straight tangents at each end where it splices to the adjoining tray. Tight vertical drops in a congested ceiling often can't take it, and a shorter radius fitting is the fix there.

Aluminum is the choice where weight and corrosion matter: this bend weighs 15.3 lb, which a single installer can handle on a lift, and aluminum doesn't need galvanizing or paint to survive damp and coastal environments. Steel tray is generally selected where you need higher load capacity per span or where a facility standard calls for it. Mixing materials in one run also raises galvanic and bonding questions, so keep the fittings in the same material as the straight sections.

Order the splice plates and bolt hardware separately. What ships here is the 90 degree vertical outside bend itself, model 6A-06-90VO36, a single Series 2-5 aluminum fitting. Each end that joins a straight section or another fitting needs a splice connection, and grounding continuity across the joints has to be handled per your bonding method.

The 6A-06-90VO36 vertical outside bend carries a CE certification. That is the only marking stated for it, so if your specification calls out a different listing, verify against the spec before releasing the order.
