The anchor member is made of a harder material as compared to the top lift member, the anchor member being made of a hard thermoplastic material and the top lift member being made of a softer thermoplastic material such as a thermoset polyurethane elastomer or a softer thermoplastic polyurethane. The anchor member may include one or more ridges for cooperatively engaging grooves associated with the head portion of the dowel pin member.
