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

A vertical outside bend carries a cable tray run over the crest of a change in elevation, where the tray rises and then flattens out, or turns down over an obstruction. The Eaton B-Line 6A-36-90VO36 makes that turn at 90 degrees on a 36 inch radius, so cable bending radius is maintained through the elevation change instead of being kinked at a hard corner. Outside means the cables ride the outside of the curve; if your run drops down and then levels off at the bottom, that is an inside bend and a different fitting.

That is exactly what it is built for. The fitting is 36 inches wide and 6 inches in height, matching a 36 inch wide by 6 inch deep Eaton B-Line Series 2 through 5 aluminum ladder tray. Width and rail depth both have to match the straight sections or the side rails will not line up at the splice. It is aluminum, so it also matches an aluminum run rather than a steel one.

Plan for 39 inches of overall length on the 6A-36-90VO36. That is the dimension you deduct from your straight sections when you lay out the run, and it is driven by the 36 inch radius. Large radius fittings eat considerably more space than a short radius one, so on a tight elevation change check your clear space above and below the tray before you commit to the 36 inch radius.

Cable bending radius. Large power and fiber cables carry a minimum bend radius from the cable manufacturer, and the tray fitting has to be at least that generous or you damage the conductor or the fiber. A 36 inch radius is the large end of the range and is what gets specified on runs carrying big MV power or fiber trunks. On a run of small control cable, a tighter radius fitting will do the same job in less space. Check the cable spec first, then pick the radius.

Aluminum. That is the usual pick for wash-down areas, coastal sites, water treatment, and outdoor runs, because it will not rust the way plain or painted steel does, and it is far lighter to handle overhead. The whole 39 inch fitting weighs 21.5 pounds, which is a one-man lift on a ladder. The trade-off against steel is load capacity, so if the run is carrying heavy cable at long support spans, verify the support spacing on the straight sections, not just the fitting.

Order the bend as the fitting only. The 6A-36-90VO36 is the 90 degree vertical outside bend body, and the connection hardware that joins it to the adjoining straight sections is specified with the tray system so that it matches the series and the material. Match aluminum hardware to the aluminum tray rather than mixing in steel splice plates on a corrosive-area run.

21.5 pounds for the 6A-36-90VO36 fitting itself. That is the dead load you add at the elevation change before any cable fill, and it is light enough for a single installer to set on trapeze hangers without a lift. Support the bend on both sides as you would any fitting rather than cantilevering it off the last straight section.

CE marked. That is what is on record for the 6A-36-90VO36 vertical outside bend, and it is what goes on the submittal for projects that call for CE. If the specification calls out a different listing or a load class, verify that against the straight section series being used on the run, since class ratings are assigned to the tray system.
