B-Line Eaton series imperial cable tray and ladder, 4" Height, 43.188" Length, 6" Width, Series 2-5 vertical inside bend, Aluminum, 90° Angle, 36" Rad

A vertical inside bend carries the tray run up or down through a 90 degree change in elevation, with the fitting bending toward the inside of the tray (the cable side of the rungs). Eaton B-Line part 4A-06-90VI36 is the aluminum version built on a 36 inch radius, so cables sweep through the elevation change on a wide arc rather than a sharp corner. If your run needs to bend away from the load side instead, that is a vertical outside bend, not this fitting.

Aluminum. That keeps the fitting light, 11.8 pounds for the whole bend, and gives you corrosion resistance without galvanizing or paint, which is why aluminum tray is common in wet process areas, wastewater plants and rooftop runs. Aluminum tray also has to stay aluminum through the run, mixing it with steel fittings creates a dissimilar metal contact and inconsistent support spans.

It is CSA certified, which is the listing most Canadian electrical inspectors and CEC-governed specs look for on tray and tray fittings.

The 4A-06-90VI36 is supplied as the bend fitting itself. Splice plates, hardware and any supports at the elevation change are ordered separately and need to match the Series 2-5 aluminum rail profile.

At 11.8 pounds it is a one-person lift, though at 43.188 inches long it is awkward enough overhead that most crews set it with two hands free and the splice plates started before letting go.
