B-Line Eaton series imperial cable tray and ladder, 6" Height, 15" Length, 18" Width, Series 2-5 vertical tee up, Aluminum, 12" Radius

A vertical tee up joins three cable tray runs where one branch rises out of the plane of the main run. The Eaton B-Line 6A-18-VTU12 is that fitting in aluminum, built for 18 inch wide tray with a 6 inch side rail height and a 12 inch radius on the vertical bend. If your branch drops below the main run instead of rising, you need the vertical tee down version, not this one.

Plan the layout around a 12 inch bend radius and an overall fitting length of 15 inches. The radius is what protects the cable from tight bending as it turns up, so if the ceiling, duct, or structure above the run leaves less clearance than the 12 inch radius sweep requires, you need a smaller radius fitting instead.

Aluminum is the material here, which is the usual pick where weight and corrosion resistance matter more than maximum load, such as outdoor runs, parking structures, and wash-down adjacent areas. Where the spec calls for steel tray, this fitting will not match the run; aluminum and steel tray systems are not interchangeable across a splice.

Yes, the fitting is UL Classified. That matters on jobs where the inspector wants the whole tray system, fittings included, to carry a classification and not just the straight sections.

Order it as Eaton B-Line 6A-18-VTU12. Reading the code: 6 inch rail, A for aluminum, 18 inch tray width, VTU for vertical tee up, 12 for the bend radius. Splice plates and hardware to tie the fitting into adjacent tray sections are ordered separately.

It weighs 13.3 lb, light enough for one person to set on a ladder, but support placement still governs. Hangers or trapeze supports should land close to the fitting on all three legs rather than letting the tee hang off the span of the straight sections.
