  • Cable length: 1 m.
  • They are made with a flexible printed circuit and SMD resistors.
  • Isolated in the outer side with two layers, one of them in a special formula above the resistances
  • system, and the other in a thick cloth in order to prevent heat loss.
  • The wire output is perpendicular to the layer for an easier anchorage.
  • They are fixed with “velcro”; and an elastic band with a locking latch.
  • With an inner reinforcement for longer life.
  • Hand finished.
