  • Patent number: 10934039
    Abstract: The present disclosure provides a support system. In an embodiment, the support system includes a top plate and a base plate. The top plate and the base plate have a common outer perimeter. The support system includes a support structure. The support structure supports the top plate above the base plate. The support system includes a pair of parallel rails. The parallel rails extend from the top plate outer perimeter to a closed end at a center portion of the top plate. The pair of parallel rails defines a channel. The support system includes a protrusion on each respective rail. Each protrusion extends into the channel in mirror-image relation to each other. The protrusions are located a fitment width distance away from the closed end. The protrusions and the closed end together define a filling position.
