The American Products Cable Manager (vendor part AM-CMP-1RU, Millennium part 521119) is a 1U, 19 in wide rack-mount unit that routes and dresses patch cords and jumpers in central office frames and equipment racks, keeping fiber and copper runs organized above and below active gear. At 1.75 in tall and 3 in deep, it fits standard rack spacing without stealing capacity from adjacent equipment. Techs use it to prevent cable strain and simplify future moves, adds and changes in the frame. Millennium also stocks compatible cable management shelves and rack-mount managers for the same 19 in rack systems.
