The first wing has a first width corresponding to the first distance, and the second wing has a second width corresponding to the second distance. The insert has an inner surface and an outer surface and is rigidly affixed to the elongated arm member within the hollow shell such that the first wing is positioned between the first and second guides, the second wing is positioned between the third and fourth guides, the inner surface of the hollow shell is positioned against the inner surface of the insert, and the outer surface of insert is positioned flush with the outer surface of the hollow shell.
