A lever (22) has an upper arm (44) cooperatively connected to a lower arm (46) with a pivot point (48) positioned between the arms (44) and (46 ). The lever (22) has a portion of the upper arm (44) extending above the top wall (16), and the lower arm (46) is positioned below the bottom wall (24). A pin (50) is cooperatively connected to the lower arm (46). When in a disengaged position the pin (50) is in the lower pin receiving opening (26).
