ABSTRACT:
A torque-limiting adapter for an elongated, insulative hot line clamp stick is provided which allows completely safe, accurate take-up of workpieces only to desired torque levels. The adapter preferably includes an elongated, tubular, axially rotatable head removably mounted onto the work end of a conventional clamp stick and housing a torque-limiting device; the input of the device is connected to the existing rotatable clamp stick, while the torque output of the device is connected to a manipulative tool, such as a pivotal hook. The tool is coupled to the head such that they rotate in unison until the desired torque level is reached, and is further coupled for axial shifting into and out of the head for safety purposes.
