Wires and cables in cable runs can be bundled in two ways: permanently, using single use cable ties made of plastic or metal, or with releasable ties made from metal, plastic or Velcro. Releasable ties will enable you to add more wires in the future, as the network expands. An additional advantage of Velcro ties is the gentle material they are made of - soft and flexible Velcro will not damage the insulation of light wires, e.g. UTP. Heavy energy wires can be bundled with releasable stainless steel ties or a ball lock tie.
