B-Line Eaton series imperial cable tray and ladder, 6" Height, 39.000" Length, 18" Width, Series 2-5 vertical outside bend, Aluminum, 90° Angle, 36" R

A vertical outside bend carries the tray run up or down over an obstruction where the cable rests on the outside of the curve, meaning the tray bends away from the cable load. Eaton B-Line model 6A-18-90VO36 turns the run through 90 degrees on a 36 inch radius. If your run has to drop or rise with the cable on the inside of the curve instead, you need the vertical inside bend version, not this one. Getting the two mixed up puts the rungs on the wrong side of the turn.

Allow for a 39 inch overall length on the fitting. The 36 inch radius is a long-sweep bend, chosen where cable bend radius rules require a gentle transition rather than a tight turn. If your ceiling space or obstruction clearance will not take that, a smaller radius bend in the same series is the fitting to look at instead.

Aluminum keeps the weight down, and this bend comes in at 17.4 lb, which matters when a two-man crew is working off lifts and hanging a long overhead run on trapeze supports. Aluminum also handles damp and corrosive environments better than plain painted steel. The trade-off is that aluminum tray generally carries less load between supports than steel of the same profile, so check your support spacing against the cable fill you are planning.

Order Eaton B-Line 6A-18-90VO36. The number reads across: 6 inch rail height, aluminum, 18 inch width, 90 degree vertical outside bend, 36 inch radius. Useful shorthand when you are matching a bill of materials against what is already installed on the job.

The 6A-18-90VO36 is supplied as the bend fitting itself. Splice plates, connector hardware and any hangers or trapeze supports for the transition are ordered separately, and you will normally need a set at each end where the fitting joins the straight run.

It carries the CE marking. That is the only marking recorded for model 6A-18-90VO36.
