Abstract: A tool is disclosed for installing an object into a cavity region. The tool includes an identifying means for providing a visual indication of an entry point for lowering the object into the cavity region. The entry point is relative to an opening in the cavity region. The tool also includes a capturing means for capturing the object after the object has been lowered into the cavity region from the entry point so as to allow the object to be retracted through the opening. The tool has a body which carries the identifying means and the capturing means. Part of the body is arranged so as to allow at least the identifying means and the capturing means to be inserted into the cavity region through the opening.
