Abstract
A tool-operated flush-mounted slam latch for a hinged door or panel comprises a slide, a cover, a cam connected to the cover, and a biasing spring for urging the slide forwardly toward a latching position. The slide is retracted to door-opening position by using a tool to operate the cam. The latch is quickly installed in a rectangular hole pre-punched in the door without use of any fastening means by merely pulling the slide rearwardly to a retracted position which is rearwardly beyond that to which the tool-operated cam is capable of retracting the slide. When installed, the cover of the latch is substantially flush with the outer surface of the door.
