Patent ID: 8210544

Claim:
An apparatus comprising: an installed seal plate having a tab thereon, the seal plate fitting between a first machinery component and a second machinery component, the tab projecting from an outer periphery of an embossment portion disposed at an outer peripheral edge of the seal plate, wherein the first machinery component and the second machinery component interact with one another to form a visible gap therebetween when the otherwise installed seal plate is not installed between the first machinery component and the second machinery component; the tab consisting essentially of an inner radial portion that merges from an outer peripheral edge of the seal plate and an outer axial portion that merges from the inner radial portion and is turned to extend in orthogonal relation to the inner radial portion along an exterior of, but not in contact with, either the first machinery component or the second machinery component, wherein the outer axial portion extends beyond a periphery of the first and second machinery components, wherein sufficient clearance is provided between an exterior of the first machinery component or the second machinery component and the outer axial portion of the tab such that the tab does not contact the first machinery component or the second machinery component; and the tab preventing installation of an additional seal plate between the first and second machinery components.
