A stepped block used to support one end of a horizontal lever which is pivoted off-center along its length, on a bolt held in a slot on the work table with the other end of the lever laid on the work, with the stepped block end of the lever on the proper step to hold the lever horizontal. Placing the long leg of the lever on the stepped block gives mechanical advantage to clamping the work in place. Tightening of the nut on the bolt places force on the step and on the work and holds the work firmly.
