ABSTRACT:
A sash lift having a base which is adapted to be fastened to the bottom rail of a sash and a handle portion mounted on the base to turn relative to the latter from an inactive position to an active position. In the inactive position, the handle portion is parallel to the frame of the sash so that a plurality of sashes may be stacked for shipping in a comparatively small space and, when the sash is installed, the handle portion is turned to the active position in which it projects outwardly from the sash rail. Coacting surfaces on the handle portion and the base prevent the handle portion from turning beyond the active position and also from turning back toward the inactive position so that the handle portion is held rigidly in the active position for service use.
