...extremely popular due to their low production (and therefore - retail) cost, their simple and easy-to-use design, and their multiple fields of use. A cable tie is essentially a thin flexible strip with a gear rack along the length of it. One end of this strip has a box with a ratchet that allows the strip to pass through it (creating a loop), but preventing it from going in reverse direction. This type of connector ensures tight binding of cables and prevents them from unbinding over time due to any physical actions. The majority of cable ties create a permanent bond, however some types can be opened for reuse.
