Abstract
Abstract A ramp member is provided for attachment with an edge of a floor mat to facilitate transportation of an object from a floor to an upper surface of the mat. A tab is provided which extends from the ramp member and defines a plane. Two projections extend from the plane of the tab out of alignment with the plane. Additionally, two cavities are formed in the ramp member adapted for receiving at least one of the two projections therein. A method of connecting ramp members is also included.
