Abstract: An apparatus including a serrated cone for interoperation with a loader. The cone includes a conical ramp portion, a cylindrical base portion, and at least one fin slot. The ramp portion defines a cone ramp surface and has a large diameter end and a small diameter end. The base portion extends longitudinally from the large diameter end of the ramp portion and has a radially outer surface. The fin slot is defined in the cone ramp surface and the radially outer surface of the base portion. The loader includes a plunger and a glider. The plunger has a fin for urging the elastomeric band along the ramp portion. The glider has a surface for engaging the elastomeric band and urging the elastomeric band over the base portion. The glider is moveably related to the plunger.
