B-Line Eaton series imperial cable tray and ladder, 6" height, 21.82" length, 42" width, Series 2-5 vertical outside bend, 30°, 24" radius, Aluminum

A vertical outside bend carries the tray run over an obstruction or down a change in elevation, with the bend turning away from the tray interior. The Eaton B-Line 6A-42-30VO24 turns 30 degrees on a 24 inch radius, so it is the fitting you use when the run has to drop or climb at that angle rather than making a horizontal turn. For a change of direction in plan, you want a horizontal elbow instead; for an inside elevation change, a vertical inside bend.

The fitting bends on a 24 inch inside radius, which is what governs how sharply the cable is forced to turn as it passes the elevation change. Check that against the minimum bending radius your cable manufacturer publishes for the largest conductor in the tray. Larger power cable often calls for a bigger radius fitting, and B-Line builds this bend in other radii for that reason.

Allow 21.82 inches of length for the fitting itself, measured along the run. That plus the 24 inch bend radius is what you need to clear structure, ductwork, or a beam before the tray straightens out again. Overall width across the rails is 42 inches.

Aluminum. That keeps the weight down, 6.7 lb for the fitting, which matters when you are hanging 42 inch wide tray off trapeze supports and when a two-man crew is setting fittings overhead. Aluminum also suits damp or corrosive areas where plain steel tray would need galvanizing or paint. Keep the hardware and splice plates compatible with aluminum to avoid dissimilar metal issues.

Order the splice connectors separately. The fitting is the bend body only, and each end has to be joined to the adjoining straight section with the splice plate and hardware specified for Series 2 through 5 aluminum tray. Budget two splice sets per fitting, one at each end.

Eaton B-Line part 6A-42-30VO24. The number reads out as 6 inch loading depth, aluminum, 42 inch width, 30 degree vertical outside, 24 inch radius, so a distributor or purchasing agent can confirm the build from the designation alone.

Yes, plan a support near the fitting. A 30 degree elevation change shifts load into the bend, and with 42 inch wide tray the span each side of the fitting should be hung per the series support spacing rather than relying on the splices. The fitting itself only adds 6.7 lb before cable is pulled in.

It is CE marked. That is the only marking carried on the record for the 6A-42-30VO24, so if your spec calls for a specific NEMA load class or a UL classification, confirm that against the series load table before you release the order.
