Abstract: A device to limit an opening of a window having a sash selectively movable between a window closed position in which the sash is received in a window frame, and a window open position in which the sash is pivoted outwardly relative to the window frame. The device includes a sash bracket, a limiting arm assembly with an engagement structure, and a securing structure with a selectively operable release mechanism. The securing structure receives the engagement structure of the limiting arm assembly so that the limiting arm inhibits pivoting of the sash toward the window open position beyond a distance of travel defined by a length of the limiting arm, and the engagement structure is releasable from the securing structure by operating the release mechanism so that the sash can be further pivoted toward the window open position beyond the distance of travel.

Abstract: A locking mechanism for use with a window having a hinge coupling a sash to a frame includes a keeper and a locking lug. The keeper includes a generally planar base plate that is abutable to a surface of either the sash or the frame and two wings extending upwardly from the base, each of the wings having an upwardly and inwardly extending portion extending from the base plate and an inwardly extending portion extending inwardly substantially parallel to the base plate from the upwardly and inwardly extending portion. The two inwardly extending portions define a gap therebetween. The planar base further includes at least one self locating leg extending outward and coplanar with the base. The self locating leg adapted to abut a portion of the sash or the frame. Thus, the keeper is positionable without a fixture.

Abstract: A device to limit an opening of a window having a hinged sash coupled to a window frame including a window opening limiting structure having a first member and a second member. One of them is securable to the sash and the other of the first member and the second member being securable to the frame. A selectively releasable coupler by which the first member and the second member are couplable is shiftable between a coupled status and a released status. The first member and the second member bridge a preselected distance such that the sash is inhibited from opening beyond a predetermined distance. The coupler is releasable so that the sash can be opened beyond the predetermined distance and re-engages automatically when the sash is closed.
