B-Line Eaton series open racks, Aluminum, Trays offer top and bottom adjustable cable support, 19" Silver powder coat, Rack mounted horizontal transi

Two rack units. At 3.5 inches of height it consumes 2U of your usable rack space, so budget for that when you lay out patch panels and active gear on an open frame rack.

It does. The tray offers adjustable cable support on both the top and the bottom, so you can route one bundle across the top surface and dress a second run underneath rather than stacking everything in one path.

Aluminum, with a silver powder coat finish. That pairs with Eaton B-Line series open frame racks in the same silver powder coat, and the aluminum body keeps it to 4 lb so it does not load up a two post rack.

A horizontal transition tray is the hand-off point between the vertical cable path on the rack uprights and the horizontal run going out to overhead ladder rack or into your patch fields. Vertical managers hold the slack going up and down the frame; the tray gives the bundle a supported turn at the level you need it. On open frame racks with no side panels, that supported transition is what keeps bend radius under control. The SB81319UT6SL handles it at 19 inch width with 6 inches of depth for the bundle to sit on.

That is MPN SB81319UT6SL from Eaton B-Line: 19 inch, 3.5 inch height, 6 inch depth, aluminum, silver powder coat, with top and bottom adjustable cable support.

Six inches of depth. That is the usable shelf the cable bundle rides on, and it is the number to check against your aisle clearance and against anything mounted directly above or below in the rack.
