A compressible resilient elastomeric pad includes a body defining a central axis, the body formed from a predetermined material and having each of a peripheral side surface, a first axial end and a second axial end, each of the first and second axial ends having a flat surface thereof disposed normal to such central axis. A first raised projection is centrally formed on the flat surface of the first axial end and a second raised projection is centrally formed on the flat surface of the second axial end. A first groove is formed in the flat surface of the first axial end in abutting relationship with a peripheral side surface of the first projection and a second groove is formed in the flat surface of the second axial end in abutting relationship with a peripheral side surface of the second projection.
