  • Easy, time-saving insulation of cable branch point where it splits into single wires.
  • Made of tough, cross-linked, Polyolefin.
  • Adhesive to relieve mechanical tension in cable harnesses.


Application Cable breakouts are manufactured from a tough cross-linked flame retarded polyolefin. This allows the breakouts to be used for both interior and exterior applications. The adhesive liner offers excellent electrical and mechanical protection and are available for 2, 3, 4, 5 and 6 core cables.
