ABSTRACT:
A clip is provided for holding a stack of at least one tray and tray cover. Stack compressive forces applied by the clip are substantially limited to tray and cover perimeter rail portions. The clip has a channel base with left and right side retaining walls attached for restricting movement of a stack in left and right directions. Left and right rods protrusions above the base extend inward towards the walls of the channel from the left and right side walls respectively for captivating the stack in an upward direction. Spring protrusions extend upward from the base on input and output ends of the channel, and are configured for applying an upward spring force on opposing bottom edge areas of the stack.
