B-Line Eaton series imperial cable tray and ladder, 6" Height, 42" Length, 30" Width, 30" and 36" Tray widths, Series 2-5 horizontal expanding tee, Al

The 6A-30-36-HT24 horizontal expanding tee joins 30 inch and 36 inch tray widths, so it is the fitting to use where a run steps between those two sizes at a branch. Model number is 6A-30-36-HT24.

It is a 24 inch radius fitting. Radius matters because tray fittings have to respect the minimum bending radius of the largest cable in the run, and 24 inch is the widest of the standard tray-fitting radii (12, 24, 36). Check your cable's published minimum bend radius against 24 inches before you commit.

Aluminum. That gives you a corrosion-resistant fitting without paint or galvanizing, which is why aluminum tray is common in wet process areas, tunnels and exterior runs. It also keeps the weight down: this tee is 39.85 lb, light enough for two people to place on trapeze supports.

It is UL Classified. For cable tray that classification covers use as an equipment grounding conductor and the tray system's suitability, which is what an electrical inspector will look for on a commercial or industrial run.

Yes, and they are separate. The 6A-30-36-HT24 is the fitting body only; each of the three connection points needs the splice plates and bolt hardware appropriate to Series 2-5 aluminum tray, plus your own supports. Order those alongside the tee so the run can be closed out in one visit.

A horizontal tee takes one run and branches it in two directions in the same plane, three openings total. A cross gives you four, for a run that continues straight through while branching both left and right. This part is a horizontal expanding tee, so it also changes tray width across the fitting, 30 inch to 36 inch. If your branch stays the same width, you want a straight tee instead of an expanding one.
