Abstract: The fastening system is used for fastening the free end of a cable to a drum of a counterbalancing system, such as the counterbalancing system of a garage door. A method for fastening the free end of a cable to a drum is also disclosed. This fastening system comprises a pressure screw and a threaded hole made through the central sleeve portion of the drum to receive the pressure screw. The thread ed hole extends from outside the drum to a central opening of the drum through whic h is inserted the shaft or an interposed element, such as a bearing. The fastening system also comprises a cable-receiving channel provided in the central sleeve portion. The channel has at least a portion that is aligned with the threaded ho le and that is adjacent to the central opening. The channel comprises a cable entry to receive the free end of the cable and is sized to tightly hold the cable therein when the drum is mounted around the shaft or the interposed element. The cable is the n pressed between the pressure screw and the shaft or the interposed element upon tightening of the screw to rigidly connect the cable by friction engagement. The fastening system is very dependable and easy to install. It also allows an insta ller or a maintenance worker to cut the cables on site from a continuous cable provided on a roll.
