Abstract
A closure mechanism for awnings and casement windows includes a flush, pivotal handle with a release mounted in a recessed housing. By depressing the release the handle is pivoted outwardly where it can be easily grasped by the user. Upon closing the window, depressing the handle allows the window to be tightly closed and latched within the frame as the handle is locked into a flush position on the window frame by a pawl which is resiliently urged into a notch in the handle within the housing.
