Panduit WMP1E PatchLink Horizontal Cable Manager, 2U Front and Rear

Two rack units of cable management on both the front and the back of the rack, with hinged covers on each side. This is the one to buy when patch cords land on the front and permanent cable comes in behind.

The fingers are molded in one piece with the bend radius built into the pass-through holes, so a Cat6A jacket cannot be pulled tight round a hard edge no matter how enthusiastically the bundle is dressed. The covers hinge up or down and stay attached, which matters the third time you open the same manager. 6.8 sq in of channel at the front and 9.1 sq in at the rear — about 62 Cat6 cords in front, 83 behind.
