A vent stop for use with a sliding member, the vent stop comprising: a housing adapted to be disposed in a recess, said housing including a cavity with a bottom plate therein, said bottom plate having a top surface forming at least a portion of an inside surface of said cavity and an edge, said edge being generally transverse to the top surface of the bottom plate; said edge extending from said top surface of the bottom plate to a bottom surface of said bottom plate, said edge forming at least one wall of an opening in said bottom plate; a tumbler disposed in said cavity, said tumbler including a protruding apex at the top thereof; a pivot means for pivotally securing said tumbler to said housing for movement between an extended position where a front face of said tumbler overlies an edge of the sliding member to prevent movement of the sliding member past the front face of the tumbler, and a retracted position within said cavity where the sliding member can be moved past the tumbler, said pivot means extending from said housing, said pivot means having an upper surface and a lower surface, and wherein said tumbler has a front and a rear end, first and second pivot members extending from the rear end of said tumbler, and wherein said first pivot member contacts said upper surface of said pivot means when said tumbler is in said extended position and said second pivot member contacts said lower surface of said pivot means when said tumbler is in an extended position, said tumbler thereby prevented from further travel; a spring means for biasing said tumbler into said extended position; and wherein said second pivot member of said tumbler contacts said pivot means when said tumbler is in a retracted position and said apex of said tumbler contacts said faceplate with said tumbler in a retracted position, said tumbler thereby being prevented from further travel.
