Claim 13:
14. A stop device for a sliding sash assembly, the sliding sash assembly for use as a door or window and including a frame defining a frame opening and a pair of sashes mounted in the frame opening and slidable relative to each other along an opening axis between a closed position and an open position, the stop device comprising:
a) a housing extending along a housing axis for mounting adjacent a travel path of one of the sashes with the housing axis extending parallel with the opening axis; and
b) a pair of depressible stop members movably mounted in the housing, the stop members spaced apart from each other along the housing axis, each stop member translatable perpendicular to the housing axis independent of the other stop member between a retracted position in which the stop member is retracted into the housing and clear of the travel path, and an advanced position in which the stop member projects from the housing into the travel path for engagement with the one of the sashes to limit movement of the sashes relative to each other toward the open position.
