B-Line Eaton series imperial cable tray and ladder, 4" Height, 25.285" Length, 9" Width, Series 2-5 vertical outside bend, Aluminum, 60° Angle, 24" Ra

A vertical outside bend carries the tray run over an obstruction or down from a higher elevation, with the bend turning away from the cable side. The Eaton B-Line 4A-09-60VO24 makes that turn at 60 degrees on a 24 inch radius, so cables ride the sweep without exceeding their bend radius. It is a fitting, not a straight section, and it bolts into the run between straights.

No, they are not interchangeable. An outside bend curves away from the cable-bearing side, which is what you want going over a beam or at the top of a drop. An inside bend curves toward the cables, used at the bottom of a drop or under an obstruction. This part is the outside version, so if your run needs the opposite curvature you have to order the inside bend in the same 9 inch width, 4 inch height and 24 inch radius.

Allow 25.285 inches of length for the fitting itself. That is the overall length dimension of the 4A-09-60VO24, and it is what you subtract from your straight section takeoff when laying out the run so the splice points land where the supports are.

What you are ordering is the bend fitting itself, model 4A-09-60VO24. Splice plates, bolts and any support hardware at the fitting are separate line items, so add them to the order along with the straight sections on either side.

Use the 60 degree when the elevation change is gradual and you have horizontal room to make it, or when a 90 would crowd structure or ductwork. A 90 turns the run straight down in a shorter footprint but pulls cable harder. This fitting is the 60 degree version on a 24 inch radius; if your drawing calls the change of direction in degrees, order to match it exactly, since a vertical bend cannot be field-adjusted.
