The Gillingham High Performance (GHP) Set Block is a heavy duty aluminum block that measure just under 3 inches long, 1 inch (~25mm) on one side, and 1.5 inches on the other. Simply slide the block between the handles at the start of the close to control the quality of your singles or reps. The GHP Set Block on the 1.5 inch side must be used as part of the GHP Gripper Challenge.
