ABSTRACT:
A tool is used to elevate and hold a garbage disposer against a sink fixture during removal and/or installation of a garbage disposer. The tool includes a flat base including a notch opening through a corner of a rectilinear base to allow an electric cord to pass around the tool. A flat load supporting platform includes a similar notch. A screw jack force applying mechanism allows the platform to be raised relative to the base. The tool works equally well with the base down or with the platform down so the user doesn't have to turn the tool over for it to work.
