B-Line Eaton series imperial cable tray and ladder, 4" Height, 17.5625" Length, 6" Width, Series 2-5 horizontal bend, Aluminum, 60° Angle, 12" Radius

Yes, that is exactly what it is built for. The 4A-06-60HB12 is a Series 2 through 5 horizontal bend with a 6 inch inside width and 4 inch side rail height, in aluminum, so it drops into a straight run of the same nominal width and depth. Mismatch either the width or the rail height and the side rails will not line up at the splice.

It turns the run 60 degrees on a 12 inch radius, measured in the horizontal plane. Pick the bend angle to match the actual change in direction on your layout, and keep the radius consistent through the run so cable bend radius stays within what the conductors allow. If your turn is a square corner, a 60 degree fitting will not get you there.

Allow for a fitting with an overall length/depth of 17.5625 inches, a 12 inch radius sweep, 6 inch width and 4 inch rail height. That footprint is what has to clear walls, ductwork and other trades at the turn, so lay it in before you cut the adjoining straight sections.

Aluminum. It keeps the fitting light (5.115 lb) for overhead work and pairs with aluminum straight sections, which is what you want for corrosion resistance in damp or coastal environments. Do not mix it into a galvanized steel run if the specification calls for a single material throughout, and remember aluminum tray is generally not accepted as an equipment grounding conductor unless the engineer says so.

Order Eaton B-Line part number 4A-06-60HB12. Reading the number: 4A is the 4 inch aluminum rail, 06 is the 6 inch width, 60HB is the 60 degree horizontal bend, and 12 is the 12 inch radius. One configuration only, so there are no finish or size options to specify.

A horizontal bend only turns the run left or right while staying at the same elevation. For a rise or drop you need a vertical inside or outside bend instead. The 4A-06-60HB12 is a 60 degree horizontal bend on a 12 inch radius, so use it for direction changes in plan view only.

The 4A-06-60HB12 ships as the bend fitting itself. Splice connectors, hold-down clamps and the supports at each side of the turn are ordered separately and sized to the 6 inch wide, 4 inch deep aluminum rail so the bolt pattern lines up.

It is CE marked. That is the only marking carried on the record for the 4A-06-60HB12 horizontal bend, so if a project specification calls out a specific listing beyond CE, verify that against the engineer's submittal requirements.
