A device for relief of strain on a cable includes a modular base for mounting, a first arm, a second arm, and a spring assembly. The first arm is pivotally coupled to the modular base. A first proximal end of the first arm is connected to the modular base at a first pivot point for pivoting of the first arm about a first rotational axis. The second arm is coupled to the modular base. A second proximal end of the second arm is connected to the modular base. The spring assembly is coupled to the first arm to provide a clamping force between the first arm and the second arm.
