  • a generally U-shaped member having a bottom portion and two generally vertical sides with the tops of each vertical side extending outward approximately 90 degrees therefrom;

    a shaft member having a diameter positioned and affixed perpendicularly to a central portion of said bottom portion of said U-shaped member, said shaft member extending upwardly therefrom parallel to and between said vertical sides having at least its upper portion threaded;

    a retention member having a width and an aperture centrally disposed therein, said aperture having a diameter larger than the diameter of said shaft member, the width of said retention member being approximately as wide as the width of said sink flange rim, said retention member positionable with said shaft passing through said aperture after the gasket, back-up ring and mounting ring has been positioned on said shaft member and said shaft member has been passed from under said sink through said sink flange sleeve in said drain opening;

    a round projection member disposed on said retention member, said projection member adapted to fit within said sink flange to center and align said shaft member within said sink flange to align said retention member on said sink flange rim; and

    a handle member having a threaded engagement aperture defined therein adapted to be screwed down on said threaded shaft member until said handle member contacts said retention member and pulls said U-shaped member upward until said U-shaped member contacts said sink, forcing said sink flange into position in said sink for the holding of said sink flange and mounting flange assembly to allow for the positioning of said snap ring into said groove in said sink flange.
