B-Line Eaton series imperial cable tray and ladder, 4" Height, 11.598" Length, 36" Width, Series 2-5 vertical outside bend, Aluminum, 30° Angle, 12" R

A vertical outside bend carries the tray run over an obstruction or down a change in elevation, bending the run away from the cable side. This Eaton B-Line piece, model 4A-36-30VO12, turns the run through 30 degrees on a 12 inch radius. It is a fitting, not a straight section, so you splice it between two straight tray lengths to make the elevation change.

Allow 11.598 inches of length along the run for the fitting itself, plus your splice plates at each end. The 12 inch radius is what sets that footprint, so if you are tight against a beam or a duct, check that dimension before you cut the adjoining straight sections.

No, and they are not interchangeable. An outside bend turns the run so the tray bottom is on the outside of the curve, used when the run rises over an obstruction. An inside bend curves the other way. Ordering the wrong one leaves you with a fitting that will not sit correctly in the run, so confirm which direction your elevation change goes before you order this 30 degree outside bend.

Aluminum keeps the weight down, which matters on long overhead runs and on the trapeze hangers supporting them. This bend weighs 5.33 lb in a 36 inch width. Aluminum also handles damp and corrosive environments without a coating, whereas steel tray normally needs galvanizing or paint for the same duty.

The 4A-36-30VO12 is supplied as the bend fitting alone. Splice plates, bolts, and any hangers or supports for the elevation change are ordered separately, and you will need a splice connection at each end of the fitting.
