US Patent 9568299 Tool for use with a two piece grommet

A tool for determining if a two piece grommet is properly installed is provided. The tool includes a housing having a button. The button is movable from an up position to a down position. In the up position, indicia is displayed indicating that the grommet is not properly installed. In the down position, indicia is displayed indicating that the grommet is properly installed. The tool further includes a cup gauge and a stroke pin assembly. The cup gauge is dimensioned to fittingly engage the cup. The stroke pin assembly includes a stroke pin and a movable support. The button rests the movable support. The actuation of a stroke pin displaces the movable part away from the button, allowing the button to fall to the down position.
