ABSTRACT:
A compact cable tension tender device includes a movable member having a first stop and a second stop spaced apart from the first stop. A first attachment may be provided on the moveable member for cable that extends in a first direction. The first attachment may engage the first stop to limit the movement of the cable in the first direction relative to the movable member. A second attachment may be provided on the moveable member for cable that extends in a second direction. The second attachment may engage the second stop to limit the movement of the cable in the second direction relative to the movable member. A resilient coupler coupled to the first attachment and to the second attachment may urge the first attachment to move in the second direction and the second attachment to move in the first direction relative to each other to maintain cable tension.
