ABSTRACT:
Locking apparatus for securing in a closed disposition a sliding door panel defined, in part, by a jamb-engaging stile which, when the panel is in a closed disposition, is received within a channel defined by frame members defining the jamb. The apparatus includes one or more locking bosses which are received within the channel defined by the frame members. The boss, or bosses, are recessed so that, when the panel is in an open disposition, they do not protrude out of the channel beyond the frame members which define the jamb. Further, the apparatus includes means carried by the jamb-engaging stile for capturing one or more of the locking bosses when the panel is in a closed disposition. Such capture apparatus precludes opening lateral movement of the door panel from its closed disposition.
