B-Line Eaton series imperial cable tray and ladder - Length 66 in, Width 12 in, Height 4 in - Aluminum

It's an Eaton B-Line Series 2-5 horizontal cross, the four-way fitting that joins cable tray runs meeting at right angles in the same horizontal plane. Model 4A-12-06-HX24 is aluminum, 4 inches deep, and built on a 24 inch radius. Use it where a main tray run intersects a branch run on both sides; for a three-way junction you want a horizontal tee instead.

This cross is built for 12 inch and 6 inch tray widths, which is what the 12-06 in the model number refers to. The 12 inch legs take the main run and the 6 inch legs take the branch. If every leg of your intersection is the same width, you need a matching same-width cross, not this mixed-width one.

It's UL Classified. For institutional and government specs that call for UL Classified cable tray fittings, that's the designation on record for this Eaton B-Line aluminum horizontal cross.

Yes, if your tray is 4 inch loading depth aluminum in 12 inch and 6 inch widths. This Series 2-5 horizontal cross is a 4 inch deep aluminum fitting, so the side rail height lines up with 4 inch tray. A 6 inch deep run needs a 6 inch deep cross; the rails won't mate otherwise.

Plan for the full fitting footprint: the 4A-12-06-HX24 measures 66 x 12 x 4 inches as catalogued, and the bends are formed on a 24 inch radius. That radius is the number that matters for cable bend protection and for clearance off walls, ceilings, and adjacent racks. Check it against your conductor's minimum bending radius before you commit the routing.

Aluminum. That keeps the piece light at 25.42 lb, which matters when a two-man crew is setting a cross overhead on trapeze hangers. Aluminum tray is also the common choice for damp, coastal, and corrosive environments where galvanized steel would need extra coating. If your spec sheet calls out steel tray, this fitting will not match the run.

Yes. A horizontal cross like the 4A-12-06-HX24 is the fitting body only; the splice plates and hardware that tie it to the straight tray sections at each of the four ends are ordered separately and must match the tray series and material. Count four connections per cross when you build the takeoff.

Count the legs. A horizontal cross has four, so a straight run continues through while branches leave both sides at the same elevation. A tee has three, for a branch off one side only. Both stay in the horizontal plane; if your run has to change elevation, that's a vertical inside or outside bend, not either of these. The 4A-12-06-HX24 is the four-leg cross, aluminum, 4 inches deep, on a 24 inch radius.
