An aperture positioned adjacent to the first end extends through the top side into the compartment. An engaging arm is elongated and has rearward end and a forward end. The rearward end is pivotally coupled to the top side adjacent to the second end and the engaging arm extends over the aperture. A piston extends through and is movably mounted in the engaging arm.
