Abstract
A sash lock for a casement window having a case with two sections of different height and with the lower level section having a top wall with a circular segment opening with a curved edge which receives a generally circular part of a rotatable operating member positioned in the opening and extending under a vertical wall interconnecting the two case sections of different height. The rotatable operating member has a curved edge of the same curvature as the curved edge of the case top wall opening as well as a peripheral flange underlying the curved edge of the top wall opening whereby in all rotative positions of the planar operating member the opening is effectively sealed.
