Standard cable ties are typically used to quickly bundle wire and cable for identification, organization, and safety. Also known as zip ties, standard cable ties are more flexible than metal ties, and are narrower than hook-and-loop ties to fit in smaller spaces. They have a tail that wraps around material and locks by inserting it into a pawl in the tie's head. As the free end of the tail is pulled, the cable tie tightens and won't come undone. Releasable cable ties can be removed and reused, while other ties are for one-time use. Cable ties are used for general or specific applications based on tie type.
