US Patent 10548414 Extruded shelving system

A product display system is comprised of extruded left and right lane members and any number of extruded center lane members. The center lane members are of inverted T-shaped configuration including a vertical center wall and upper and lower base elements extending from opposite sides. The lower base elements are formed across their entire width with closely spaced, alternating grooves and projections. The upper base elements have elements at outer edges thereof to engage with a selected groove and/or projection of an adjacent lane member to form a lane of desired width. Pushers are mounted on the vertical walls to maximize the area available for grooves and projections.
