Abstract
Abstract A cable drum is cut away to provide a drum pocket to receive enlargement such as a ferrule on the end of a cable. The drum pocket is set at an angle with respect to the departure line of the cable from the drum so that the spring tension of the bent cable maintains the ferrule in the drum pocket. Opposed shoulders on the drum pocket and a cable departure slot leading therefrom maintain the ferrule in the drum pocket until the cable is completely unwound from the drum and quick release is required.
