B-Line Eaton series open racks, Aluminum, Trays offer top and bottom adjustable cable support, Flat black powder coat, Rack mounted horizontal transi

Yes. The tray is 19 inches wide, which is the standard EIA rack mounting width, and it is designed to mount horizontally in the rack. Height is 3.5 inches, so it occupies 2 rack units of panel space.

It does. The tray provides adjustable cable support on both the top and the bottom, so you can route one bundle over and another under the same tray and tune the support position to the bundle diameter rather than being fixed at one height.

Depth is 3.5 inches, same as the height, so it sits shallow in the frame and won't crowd equipment mounted behind it. Total weight is 4 lb, light enough to hold in place single-handed while you start the mounting screws.

Aluminum construction with a flat black powder coat. The aluminum keeps the part at 4 lb and avoids rust in conditioned telecom and data spaces, and the flat black matches the common black open-frame rack and ladder rack finish.

It is the handoff point between cable coming off overhead ladder rack or runway and the vertical managers on the rack itself. Mounted horizontally in the 19 inch rack opening, the tray carries the bundle across the face of the rack and its adjustable top and bottom supports hold the cable at a controlled bend as it turns down into the equipment. It is cable management hardware, not a shelf for equipment.

Plan on 2U. At 3.5 inches tall in a 19 inch rack, it consumes the same panel space as a 2U device, so leave two open mounting positions where you want the cable to cross.
