<p>An alignment device (412) is located on a mandrel (408) of an installation tool (400) and is used to align a structural member (402) in an opening of a workpiece (404) while seating a radial flange (414) of the structural member against a first surface (411) of the workpiece. The alignment device comprises a disk-shaped device having an outer surface, an inner surface forming an opening (410) through the alignment device, and where the opening is sized to be at least slightly smaller than a major diameter of an expansion portion (406) of the mandrel. In one embodiment, the alignment is nylon to allow the inner surface of the alignment device to be repeatedly, radially expanded and yet the opening formed by the inner surface returns to its original size.</p> |
