B-Line Eaton series imperial cable tray and ladder, 4" Height, 20.625" Length, 36" Width, Series 2-5 horizontal bend, Aluminum, 30° Angle, 12" Radius

Yes, that is exactly what it is built for. The 4A-36-30HB12 is a 36 inch wide, 4 inch deep aluminum horizontal bend in the B-Line Series 2-5 imperial cable tray family, so it mates to straight ladder sections of the same 36 inch width and 4 inch side rail height. Mixing widths or rail depths at a fitting is where runs go wrong, so match both numbers, not just the width.

It turns 30 degrees on a 12 inch radius. The 12 inch inside radius is the tight one in B-Line's imperial bend range, so it is the choice when the tray has to change direction in a congested ceiling rather than sweep. Plan the layout around the fitting's own 20.625 inch length dimension plus the 36 inch width envelope through the turn, and check your cable bend radius requirement against a 12 inch radius before you commit.

The fitting is CSA certified. That is the listing that inspectors on Canadian projects and many industrial specs ask for on cable tray, so it can go into a run where CSA certified components are called out.

Order it as Eaton B-Line 4A-36-30HB12. Read that as 4 inch deep aluminum, 36 inch width, 30 degree horizontal bend, 12 inch radius. Distributors should quote against that full string, since changing the trailing radius digits or the leading depth gives you a different fitting that will not line up with the run.

Plan on ordering connection hardware separately. The 4A-36-30HB12 is the bend fitting itself, a 36 inch wide aluminum Series 2-5 horizontal bend. Splice plates, hardware kits and the support brackets or trapeze steel are separate line items on a tray order, so count two splice sets per bend, one at each end.

7.776 lb for the fitting itself. That is the bare fitting, not the loaded weight, so size your trapeze or wall bracket for the cable fill you are pulling through the turn. Bends want a support close to each end connection rather than being hung mid-span off the adjoining straight sections.
