Black Box Rackmount Cable Raceway, Double-Sided, Vertical, Side Mount - Raceway RMT202A-R3

Tangled cable clutter is the pits, but organizing cable is a winning idea. If you mount a cable raceway on your distribution rack, you can get rid of cable clutter forever. The slotted ducts provide ample space for all your cables, while the new passthrough holes allow the cables to be routed from the front to the back of the cable manager. Single-sided and horizontal raceways are also available.
