ABSTRACT:
A clamping plate assembly for movement laterally into and out of engagement with a load includes a main plate member which has front, rear, upper and lower edges. Along the lower edge of the main plate member, an auxiliary plate overlies a portion extending from the lower edge a predetermined distance toward the upper edge thereof, and is removably attached to the main plate member. A yieldable friction material then is over substantially the major portion of the auxiliary plate and the portion of the main plate member not covered by the auxiliary plate.
