Abstract

A push-on gripper plate for use in securement of a mesh screening means on the protruding, threaded, end portion of a rock bolt inserted into a rock face is disclosed. The gripper plate has a generally planar base portion adapted to overlie the mesh screening means and a central opening in the base portion having two or more leg portions positioned on the perimeter of the opening and inclined downwardly, inwardly toward the centre of said opening below the plane of the base portion. A plurality of tab portions are positioned on the perimeter of said opening in alternating arrangement with said leg portions, the tab portions being inclined downwardly, inwardly toward the centre of the central opening below the plane defined by the base portion.
