B-Line Eaton series imperial cable tray and ladder, 4" Height, 25.285" Length, 18" Width, Series 2-5 vertical outside bend, Aluminum, 60° Angle, 24" R

A vertical outside bend carries the tray run up or down over an obstruction where the cables bend away from the tray bottom, so the fitting turns the run outward from the cable side. The B-Line 4A-18-60VO24 makes that turn at 60 degrees on a 24 inch radius. If your run has to change elevation the other direction, with the cables bending toward the tray bottom, you need a vertical inside bend of the same width, depth and radius instead. Getting the two mixed up is the most common ordering mistake on elevation changes.

Allow at least 25.285 inches of overall length for the fitting itself, measured along the run. That is the published length of the 4A-18-60VO24, and it comes from the 24 inch bend radius plus the straight tangents at each end. The bend turns 60 degrees, so lay out your straight sections off the end tangents rather than off the theoretical centerline intersection.

Order Eaton B-Line 4A-18-60VO24. Reading the code: 4 inch rail height in aluminum, 18 inch width, 60 degree vertical outside bend, 24 inch radius. The adjacent numbers in the family change only one of those values at a time, so confirm all four before releasing the order.

The 4A-18-60VO24 is supplied as the bend fitting itself. Splice plates and their bolt and nut sets are ordered separately, and you need a set at each end of the fitting where it joins the straight tray. Plan on matching the splice plate to the same Series 2-5 aluminum tray the fitting is built for.

Yes. The 4A-18-60VO24 vertical outside bend is CE marked. That is the only certification carried on the record for it, so if your submittal also calls for a specific load class test report, request that documentation separately.
