Abstract
A device for latching a sliding door member in place against a stationary frame structure includes an elongated hasp mountable on the door and engageable with a keeper secured to a bracket on the frame with which the hasp engages preventing it from moving laterally outwardly. A pair of cam elements are pivotally mounted on the bracket for movement about a common axis above the hasp, and have flat end surfaces directly overlying an end edge of the hasp for latching it against vertical upward movement. A stop pin on the bracket below such common axis engages with the cam elements for permitting one of them to pivot in only one direction while permitting the other cam element to pivot in only an opposite direction so that the hasp remains latched against vertical upward movement by one or the other of the cams even when subjected to forces having a tendency to cause the cams to pivot in either such direction.
