ABSTRACT:
An operator for controlling the movement of a window sash generally pivotable relative to a frame about a first edge between open and closed positions includes a first arm having a first end slidably attachable to a second edge of the window sash opposite the sash first edge. A second arm has a first end also slidably attachable to the sash second edge, and is further pivotally secured to the first arm. A base is attached to a frame and includes a drive attached to the other ends of the first and second arms for pivoting the first arm relative to the second arm whereby the first ends and second ends of first and second arms are disposed together with a window sash in an open position and the first ends and second ends are spaced apart with a window sash in a closed position. A connector for slidably attaching an operator arm to a window sash includes a metal track attachable to a window sash, a plastic shoe translatable along the track, and a plastic post pivotally secured to the shoe by a metal rod substantially parallel to the track. The post is disposable through an opening in the operator arm so that an end of the post protrudes from the opening. A plastic clip is disposed about the end of the post for securing the post in the operator arm opening.
