A system for securement of a mesh screening means on the protruding, threaded end of a rock bolt inserted into a rock face, comprises a push-on gripper plate having a generally planar base portion adapted to overlie the mesh screening means. The planar base portion has a magnetically grippable contact surface for operative engagement with an installation tool. An installation tool is provided having a handle portion with a main body portion rigidly attached thereto. The main body portion has a means for exerting an attractive magnetic force to operatively magnetically engage the magnetically grippable contact surface of the gripper plate, and a cavity dimensioned and adapted to non-fractionally receive the end of the rock bolt during installation of the gripper plate. A ramming means 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.
