B-Line Eaton series imperial cable tray and ladder, 4" Height, 14.892" Length, 36" Width, Series 2-5 vertical outside bend, Aluminum, 60° Angle, 12" R

A vertical outside bend carries the tray run over an obstruction or down a change in elevation, with the bend turning away from the cable fill side. Model 4A-36-60VO12 turns 60 degrees on a 12 inch radius, so it is the fitting you use where the run has to break pitch by 60 degrees going over something rather than under it. If your run needs to turn upward into the tray's inside face instead, that is a vertical inside bend, not this part.

The 4A-36-60VO12 bend is UL Classified. That matters on specs that call for a UL Classified tray system used as an equipment grounding conductor, and it is the line a specifier normally wants to see on the submittal.

The fitting itself is formed on a 12 inch radius, which sets the minimum sweep the cable sees going over the bend. Check that against the minimum bending radius of the largest cable in the tray; if your cable needs more than 12 inches, step up to a larger radius version of the same 60 degree vertical outside bend rather than forcing the cable through this one.

Allow for the fitting's own 14.892 inch length along the run, measured on the 12 inch radius. Contractors usually cut the adjoining straight sections to suit after the bend is set, so lay out the elevation change first, place the bend, then field-cut the straights.

Aluminum is what this bend is made from. It is the usual pick where weight and corrosion resistance drive the job, and at 7.552 lb for a 36 inch wide 60 degree bend one person can set it on the supports. If the spec calls for a hot dip galvanized or stainless run, you need the matching material in the same series rather than this fitting, since tray systems are not mixed across materials at a splice.

Yes. The bend is the fitting only, so plan on splice plates and hardware at each connection to the adjoining straight sections, plus whatever support hardware the run calls for at the elevation change. Order the splice plates that match Series 2-5 aluminum tray.
