ABSTRACT:
A sliding patio door includes a movable panel and a stationary panel, the panels including vertical frame members which overlap when the door is closed. A bolt through one of the vertical frame members engages a nut in the other vertical frame member when the door is closed to draw the frame members together, eliminating clearance between them and locking the panels together against horizontal and vertical movement. The bolt is engaged and disengaged by 90.degree. rotation. When the bolt is disengaged, a captured compression spring keeps it at its open position for convenience.
