ABSTRACT:
A tool for installing a locking ring in an annular groove defined by a lower annular rim portion of a sink flange of a garbage disposer sink flange assembly. The tool includes a pair of elongated members that are pivotally connected at a pivot point to form a pair of opposed handles and a pair of opposed ring-engaging tips. The tips define a pair of outwardly facing indentations that adapt the tips to engaging the locking ring in order to spread the locking ring by operation of the person squeezing the handles toward each other. Mechanical stops are located in the opposing handles that prevent excessive spreading of the locking ring. In addition, the tool is configured such that when the tool is brought into position, and the tool is leaned over the locking ring is released from the ring-engaging tips.
