B-Line Eaton series imperial cable tray and ladder, 6" Height, 32.692" Length, 6" Width, Series 2-5 vertical inside bend, Aluminum, 30° Angle, 48" Rad

A vertical inside bend carries the tray run up or down through a change in elevation, with the fitting turning toward the inside of the angle. Eaton B-Line model 6A-06-30VI48 makes that transition at 30 degrees on a 48 inch radius, so cable bending radius stays controlled through the elevation change. Use it where the run has to climb over an obstruction or drop to a lower tier rather than turn horizontally.

Inside versus outside is about which way the tray rails curve relative to the angle, not simply up versus down. An inside bend turns the run toward the concave side of the elevation change, an outside bend toward the convex side. Model 6A-06-30VI48 is the inside version at 30 degrees. Sketch the elevation before ordering, because ordering the wrong one of the pair is the most common mistake on a tray run with a vertical offset.

Plan on 32.692 inches of run length for the fitting itself. That is the dimension to subtract from your straight section layout before cutting, and it is driven by the 48 inch radius: a tighter radius fitting at the same 30 degrees would consume less. Lay it out before you order straights so you are not field cutting.

Aluminum construction keeps the fitting light, 7.5 pounds for this 6 inch bend, which matters when one person is setting fittings on a lift or overhead. Aluminum also handles damp and corrosive indoor environments without a coating. If your spec calls for a steel or galvanized tray system, this fitting is not the match, since fittings have to share the material and series of the run.

Splice plates, bolts and any hanger or trapeze support are ordered separately from the fitting. Budget a pair of splice connections for the bend, one at each end where it joins the straight sections, and confirm the splice type matches Series 2-5 aluminum tray.
