Patent ID: 10724254

Abstract:
A levelling system for aligning surface coverings includes a tab with a substantially flat base and a vertical member extending away from a central area of the top surface of the base. The base includes beveled feet portions on opposite sides thereof to allow it to be more easily inserted under lower surfaces of adjacent surface coverings, with the vertical member extending between opposed edges or ends of the tiles. The vertical member is attached to the base by reduced width frangible leg portions held in rounded openings, below the top surface of the base. The vertical member includes an opening spaced so as to be above two adjacent tiles when the tiles are placed on the base on either side of the vertical member. When a wedge is inserted and held in the opening and presses down, the tiles are pushed downwardly toward a surface upon which they are being laid to properly align the edges thereof until the tiles are set, the wedge removed and the vertical member broken off at the frangible leg portions.
