B-Line Eaton series imperial cable tray and ladder, 6" Height, 21.188" Length, 12" Width, Series 2-5 vertical inside bend, Aluminum, 90° Angle, 12" Ra

A vertical inside bend turns the tray run up or down through 90 degrees with the bend curving toward the inside of the tray (the cable-carrying side). Eaton B-Line model 6A-12-90VI12 is the aluminum version for 12 inch wide, 6 inch deep Series 2 through 5 ladder tray, with a 12 inch bend radius. Use it where a run has to climb a wall or drop into a cabinet without exceeding the cable's bend radius.

Allow 21.188 inches of overall length for the fitting itself, plus the straight tray on either side. That is the dimension to use when you are laying out a wall climb or a drop into gear and need to know where the next straight section starts.

CSA certification is listed for the 6A-12-90VI12 aluminum bend, which is what most Canadian electrical inspectors want to see on tray fittings.

The 6A-12-90VI12 is aluminum, which is why the fitting weighs only 9 lb despite being 12 inches wide. That matters for overhead work where crews are lifting fittings on a ladder, and aluminum does not need galvanizing to resist corrosion. If your run is steel tray, order the steel version of the fitting instead so the rails and splice holes line up in the same material.

Both turn the run 90 degrees in the vertical plane; the difference is which way the tray curves. On an inside bend the rungs stay on the inside of the curve, so the tray sweeps up as if hugging the wall. An outside bend curves the other way, with the cables on the outer face. They are not interchangeable, so confirm which direction your run turns before ordering. The 6A-12-90VI12 is the inside version in 12 inch width with a 12 inch radius.

Order Eaton B-Line 6A-12-90VI12. That breaks down as 6 inch rail height, aluminum, 12 inch width, 90 degree vertical inside bend, 12 inch radius. Splice plates and hardware to join it to the adjoining straight sections are ordered separately.
