Abstract
An example cable tension device is provided. The cable tension device includes a bracket, an arm, and a spring. The arm is rotatably coupled to the bracket and comprises a roller bar to receive a cable of an overhead door. The spring is coupled to the arm. The spring is under a load to cause the arm to rotate away from the bracket to maintain a tension on the cable.
