The device includes a base having a top surface, a bottom surface, and a perimeter edge extending between the top surface and the bottom surface. A conduit extends through the base between the top surface and the bottom surface. A rod extends through the conduit. The rod is slidable within the conduit. A first block is coupled to a first end of the rod. A second block is coupled to a second end of the rod. The rod has a length greater than a length of the conduit such that the second block is in an extended position spaced apart from the base when the first block is positioned adjacent to the base.
