Abstract: A manually operable device for depressing push button control buttons associated with a distantly located control box having opposed surfaces employs a motion transmitting flexible control cable assembly having a sheath element elongated between a user operated extremity and responsive distal extremity, and a core element slideably disposed within the sheath element. The distal extremity of the sheath element is secured by a receiving head adapted to be adjustably positioned upon an elongated straight bar. Two facing clamping components adjustably engage the bar on opposite sides of the receiving head and are adapted to forcefully interact with the opposed surfaces of the control box.
