B-Line Eaton series imperial cable tray and ladder, 6" Height, 41.25" Length, 30" Width, Series 2-5 horizontal bend, Aluminum, 45° Angle, 36" Radius

That is exactly the run it is built for. The 6A-30-45HB36 is a 30 inch wide, 6 inch deep aluminum horizontal bend, so it matches a straight section of the same 30 inch inside width and 6 inch side rail depth. Mixing widths at a fitting does not work, the side rails have to line up, so confirm your straight sections are 30 inch width and 6 inch rail before ordering this one.

Plan on a 41.25 inch overall length for the fitting, measured along its longest dimension, with a 36 inch centerline radius on the 45 degree turn. In a congested ceiling or a pipe rack that is the number that decides whether the turn fits, a 36 inch radius bend swings well outside the tray width itself. If the space will not take it, a tighter radius bend in the same series is the move.

A horizontal bend turns the run left or right at a constant elevation. It will not take you up or down. To change height, for example to drop under a beam or rise over ductwork, you need a vertical inside or outside bend instead. The 6A-30-45HB36 is the 45 degree horizontal turn, so use it where your run changes direction on plan only.

If the existing run is 30 inch width with 6 inch side rails in aluminum and the corner turns 45 degrees, the 6A-30-45HB36 matches on all four counts. The one thing to check on site is the radius of the fitting coming out, since a 36 inch radius bend occupies more floor or ceiling area than a short radius one. If the old corner was tight to a wall or column, measure before you pull it.

Bend radius is a cable protection spec, not just a geometry choice. A 36 inch radius turn keeps large power conductors and fiber inside their allowable bending radius through the corner, which a short radius fitting will not do. If your run is small control or instrument cable, a tighter radius fitting saves space and money. If you are pulling big feeders or fiber, the 36 inch radius is the one the cable spec is asking for.

Aluminum. For exterior runs, coastal sites, water treatment, food plants and parking structures, that is usually what you want, since aluminum does not rely on a coating the way painted or galvanized steel does. Aluminum is also roughly a third the weight of steel for the same section, which matters when crews are lifting fittings overhead. This one weighs 17.2 lb.

It carries CSA certification, so it will clear a Canadian inspection on that basis. Worth knowing if you are specifying a run that crosses into Canada or working to a spec that calls out CSA certified tray components.

Yes, plan on connectors at each end. Tray fittings land between straight sections and the splice hardware is ordered as its own line item, matched to the tray series and to aluminum so you are not mixing metals at the joint. Also figure on a support within the distance your series requires on either side of the bend, since a fitting is not a self supporting span.
