Multi Block Hanger for 4X LCF158 (Kit of 20). Multi block hanger support systems are designed for organizing bundled runs of coax cable. Each space-saving block securely holds two runs of coax, allowing a compact bundle of up to six runs to be supported by stacking three blocks. Multi Blocks are manufactured of durable glass polypropylene providing thermal, chemical and UV resistance in extreme environments. They come pre-assembled with the necessary hardware to connect to M8 threaded holes or 8.5mm (0.335in) through holes. Can also be mounted to Angle Member Adapters (purchased separately).
