Telescoping Push Bar Operators are designed for residential use as a means of opening and closing sashes with fixed screens. They are most commonly used for holding open outward-projected windows which are screened from the inside. The Push Bar cams cover the nylon escutcheon and compresses the spring so that the window is pulled tightly to the frame which helps to eliminate air infiltration. Sliding action of the Aluminum Push Bar through the nylon escutcheon insures smooth operating and long wearing movement.
