B-Line Eaton series imperial cable tray and ladder, 6" Height, 35.677" Length, 18" Width, Series 2-5 vertical outside bend, Aluminum, 60° Angle, 36" R

It turns a ladder tray run downward over an obstruction or a drop, bending the run 60 degrees on a 36 inch radius. Outside bend means the tray's load surface is on the outside of the curve, so the run rises to the fitting and then pitches down away from it. Inside bends handle the opposite direction, where the run pitches up. It is part of the Eaton B-Line imperial Series 2-5 ladder tray system, 18 inches wide with a 6 inch side rail height.

Yes, if your straight sections are Eaton B-Line imperial Series 2-5 ladder tray in the same 18 inch width and 6 inch rail height. The 6A-18-60VO36 is built to those dimensions and in aluminum, so rail depth, width and material all match a 6 inch aluminum 18 inch run. It will not mate cleanly to a different rail height or width without a reducer or transition piece.

Allow for a fitting that measures 35.677 inches along its length and 18 inches across, swinging through 60 degrees on a 36 inch centerline radius. On a tight ceiling drop or close to a wall, that 36 inch radius is the number that decides whether the fitting clears. If headroom is short, a smaller radius bend or a lower bend angle is the fitting to specify instead.

Depends which way the tray face turns. A vertical outside bend carries the run over the crest of a change in elevation, with the cables on the outside of the curve, so it is what you use where a level run pitches down over an obstruction or off a ceiling. Where the run bottoms out and turns back up, that is a vertical inside bend, a different part number. Getting the two mixed up is the most common ordering error on elevation changes, so confirm the direction of the turn from the elevation drawing before you order.

Plan on ordering splice plates and hardware separately. The 6A-18-60VO36 is supplied as the 60 degree vertical outside bend section itself; each end still needs a splice connection to the adjoining straight run, so count two splice sets per fitting when you build the takeoff.

That is the main reason to specify a large radius fitting. The 36 inch radius sets the curve the cables follow through the elevation change, so heavy power or fiber runs with a large minimum bending radius are supported by the tray rather than being forced tighter than the cable allows. Check the largest cable's published minimum bending radius against the 36 inches before committing.

Order it as Eaton B-Line 6A-18-60VO36. The number reads directly: 6 inch rail, aluminum, 18 inch width, 60 degree vertical outside bend, 36 inch radius. That is the number to put on a distributor purchase order or a submittal.
