B-Line Eaton series imperial cable tray and ladder, 4" Height, 39.304" Length, 24" Width, Series 2-5 vertical inside bend, Aluminum, 60° Angle, 36" Ra

Plan on 39.304 inches of overall length for the fitting itself. That is the dimension to deduct from your straight sections when you lay out the run, and the 36 inch radius means you need clearance on the swing side of the bend before any wall, beam or ceiling obstruction.

A vertical inside bend carries the tray run up or over an obstruction while keeping the cables on the inside of the turn, so the bend radius supports the cable rather than pinching it. The Eaton B-Line 4A-24-60VI36 turns the run through 60 degrees on a 36 inch radius. Use an inside bend where the tray changes elevation and the cable bundle sits on the concave side; an outside (VO) bend is the fitting when the cable rides the convex side of the change.

Yes, the 4A-24-60VI36 aluminum vertical inside bend is UL Classified, which is what most specs and inspectors look for on a tray system used as an equipment grounding path or in a classified installation.

Bend radius is driven by the minimum bending radius of the cable you are pulling. Large power and fiber cables typically require a generous radius, and the 36 inch radius on this fitting gives that room. If your cable spec allows a tighter turn, a smaller radius fitting shortens the run and saves space; if it does not, a tight bend damages insulation during the pull.

Order Eaton B-Line model 4A-24-60VI36. That number breaks down as 4 inch rail height, aluminum, 24 inch width, 60 degree vertical inside bend, 36 inch radius, so a distributor can confirm it against the tray schedule at a glance.

The fitting weighs 12.088 lb, light enough for a two-man overhead set on trapeze hangers. Because it is aluminum, it also keeps the dead load on the support structure lower than a steel equivalent of the same 24 inch width.

The 4A-24-60VI36 is the bend fitting itself. Splice plates, connection hardware and the hangers or trapeze supports on each side of the fitting are separate line items, so add them to the order if your run does not already have them staged.
