B-Line Eaton series imperial cable tray and ladder, 4" Height, 13.692" Length, 30" Width, Series 2-5 vertical inside bend, Aluminum, 30° Angle, 12" Ra

A vertical inside bend turns the tray run upward or downward with the cables riding on the inside of the curve, so it is the fitting you use when the tray changes elevation and the cable bundle stays on the concave side of the turn. The B-Line 4A-30-30VI12 makes that change at a 30 degree angle on a 12 inch radius. If the cables would ride on the convex (outer) side of the elevation change, that is an outside bend fitting, not this one.

Plan on 13.692 inches of length for the fitting itself, measured along the run, on a 12 inch inside radius. Lay that out against your ceiling or wall obstruction before you cut the straight sections, since the bend eats into the dimension between supports.

Yes. The 4A-30-30VI12 vertical inside bend is UL Classified, which is what most inspectors and specs look for when cable tray is used as an equipment grounding conductor or where the drawing calls out a listed tray system.

The 4A-30-30VI12 is supplied as the bend fitting only. Splice plates, bolts, and the support hardware for the run are ordered separately and need to match the Series 2 through 5 aluminum rail you are joining it to.

Order it as 4A-30-30VI12, an Eaton B-Line series imperial cable tray fitting: 4 inch rail height, 30 inch width, 30 degree vertical inside bend, 12 inch radius, aluminum.

It weighs 4.96 lb. At 30 inches wide it is awkward to handle overhead more than it is heavy, so a single installer can set it, but it needs to be supported at both splice points while the splice plates are bolted up.

Aluminum tray is the usual pick where weight on the structure matters and where corrosion is a concern, such as damp or coastal environments, without the cost of a coating. This bend is aluminum throughout. If your spec calls for steel or a hot dip galvanized tray, this fitting is not a substitute for it.
