    Abstract: A window opening limit device includes a substantially planar base and a sash stop pivotally engaged with the base between a first stop position and a second stop position. The sash stop is adapted to pivot about a first axis substantially parallel to the planar base. A catch is pivotally engaged with the base between a first catch position and a second catch position, and is adapted to pivot about a second axis substantially perpendicular to the planar base. When in the first catch position, the catch is engaged with the sash stop, and when in the second catch position, the catch is disengaged from the sash stop.
