B-Line Eaton series imperial cable tray and ladder, 4" Height, 22.092" Length, 6" Width, Series 2-5 vertical outside bend, Aluminum, 45° Angle, 24" Ra

A vertical outside bend carries the tray run up and over an obstruction or a change in elevation, with the fitting bending away from the cable side. The B-Line 4A-06-45VO24 does that at 45 degrees on a 24 inch radius, so the cable follows a generous curve rather than a sharp break. Use it where the run has to pitch down or rise over ductwork, beams, or pipe without exceeding the cable's bend radius.

Plan for 22.092 inches of length for the fitting itself. That is the figure to subtract when you cut or order the adjoining straight sections, and it is why a 24 inch radius bend needs to be laid out before you fix hangers either side of the elevation change.

The 4A-06-45VO24 is UL Classified. For tray used as an equipment grounding conductor or where an inspector is checking listed tray fittings, that classification is the mark on the fitting.

The 24 inch radius is the generous option in the vertical bend range, and it is the one specified when the cable's own minimum bending radius rules out a tighter fitting. Large diameter power and shielded cable typically call for a bend radius many times the cable OD, so check the cable manufacturer's minimum against 24 inches before committing. Smaller radius fittings exist for control and instrumentation runs where the cable bends tighter.

Order it as B-Line 4A-06-45VO24. That number reads as the fitting's dimensions: 4 inch rail height in aluminum, 6 inch width, 45 degree vertical outside bend, 24 inch radius.
