B-Line Eaton series imperial cable tray and ladder, 4" Height, 33.539" Length, 6" Width, Series 2-5 vertical inside bend, Aluminum, 45° Angle, 36" Rad

A vertical inside bend carries the tray run up or down a 45 degree change in elevation with the fitting curving toward the inside of the turn, so the cables stay inside the tray profile through the transition. The B-Line 4A-06-45VI36 does that at a 36 inch radius, which is the bend radius the cable sees going through it. If your elevation change turns the other way (tray dropping away from the load side), you need the matching vertical outside bend instead.

Allow 33.539 inches of developed length for the fitting itself. That is the dimension to subtract from your straight sections on either side of the elevation change when you take off the run at a 36 inch radius.

Aluminum is the lighter option and is the common choice where corrosion is a concern, such as exterior, damp, or process areas. This bend weighs 6.5 lb, which one electrician can set in place on a ladder without a second pair of hands. If your run is already galvanized steel tray, stay with steel fittings so the splice hardware and finishes match.

It does. The 36 inch radius sets the minimum bend the conductors take through the elevation change, so large power cable with a big minimum bending radius gets routed without damage. Smaller radius fittings are available in the same series if the cable allows it and you are tight on space, since a 36 inch radius bend eats 33.539 inches of run length.

Order it as 4A-06-45VI36 from Eaton's B-Line series. Reading the number: 4 inch rail height, aluminum, 06 inch width, 45 degree vertical inside, 36 inch radius. Splice plates and hardware are separate line items on B-Line tray work.
