An apparatus for use in a well. The apparatus comprises a mandrel containing a radial shoulder, a sub member concentrically disposed about the mandrel, and an upper slip, concentrically disposed about the mandrel, for engaging the well. The apparatus further comprises an upper cone abutting an underside of the upper slip, and wherein the upper cone is disposed about the mandrel, and an elastomer operatively associated with the upper cone, and wherein the elastomer is disposed about the mandrel. The apparatus further includes a lower slip, concentrically disposed about the mandrel, for engaging with the internal portion of the well, and lower cone abutting an underside of the lower slip, and wherein the lower cone is disposed about the mandrel, and wherein the lower cone is operatively associated with the elastomer. The apparatus further contains a first alignment member selectively connecting the sub with the upper slip, and wherein the first alignment pin is selected to shear at a first predetermined force.
