The installation tool has a handle portion with a main body portion rigidly attached thereto. The main body portion has a magnet to magnetically engage the magnetically grippable contact surface of the gripper plate, and a cavity dimensioned and adapted to non-frictionally receive the protruding, threaded end of the rock bolt during installation of the gripper plate. A ram is rigidly attached to the opposite other end of the handle portion of the installation tool. A method of installing a gripper plate onto the protruding, threaded end of a rock bolt is also provided.
