Abstract: A grab plate assembly for retaining an inner cylindrical tube in a fixed telescopic position relative to an outer cylindrical tube in a telescoping post. The assembly comprises a grab plate having a polygonal tube receiving opening therein, a lever arm integral with and angled relative to the grab plate, and an actuating rod. Turning the actuating rod in a first direction lifts the lever arm causing multiple side edges of the tube receiving opening to compressively engage multiple points on the inner cylindrical tube thereby resisting telescopic movement of the inner cylindrical tube relative to the outer cylindrical tube. Turning the actuating rod in a second opposite direction lowers the lever arm causing the side edges of the tube receiving opening to disengage from the inner cylindrical tube and to permit telescopic movement of the inner cylindrical tube relative to the outer cylindrical tube.
