The CommScope FDF Series Cable Clamp Kit (E-501-L40, Millennium part 519718) secures 8 in runs of IFC or OSP cable entering FDF frames, holding cable position and taking strain off terminations as cables route into the rack. It mounts directly to FDF frame hardware alongside existing bays, so it fits into racks already running the FDF platform. The kit is built for both indoor distribution cable and outside plant cable entering the same frame. Stock it with FDF isolation pads and guard box kits to finish the frame's cable entry.
