The CommScope FDH 3000 Cable Management Hardware (FPS-MPPRACKMTCM, Millennium part 521117) is a 2U putty white rack accessory that routes and dresses fiber and copper jumpers on FDH 3000 frames, keeping cross-connects from tangling as ports get added over time. It mounts directly into the FDH 3000 rack system without additional brackets. Techs use it to maintain clean, traceable jumper runs during moves, adds, and changes on splitter and cross-connect panels. Millennium also stocks matching FDH 3000 splitter panels and modules for the same platform.
