ABSTRACT:
A tool for installing a garbage disposal to a sink flange extending below a sink includes a keeper and a platform. The keeper includes a head portion for engaging the sink flange above the sink and a leg portion extending along the sink axis through the sink flange. The platform carrying disposal mounting rings is releasably engaged with the leg portion below the sink to position it adjacent to and aligned with the end of the sink flange body. A snap ring is biased from the platform onto the flange body and into the annular groove in the flange body to trap the back-up ring and mounting ring on the flange body below the sink. The platform is disengaged from the leg portion and the tool is removed so that the disposal may be secured to the mounting ring in a known manner.
