Despite twists, tweaks, or turns, these cables will never let up. Resilient and flexible strain reliefs: built with repeated use in mind, These cables have longer and more flexible strain reliefs to ensure that the point where the cable Meets the connector does not fail. High-strength aluminum connectors:  Designed to withstand forces up to 30 lbf (130N), these aluminum connectors were engineered to defy the rigors of odd bends and strains. It will take a force greater than 130N to get these connectors to even begin to bend.
