Recommended for use on narrow windows, or for round-top and trapezoid windows that use a butt hinge. Sash weight should be limited to 40 lbs. to insure ease of operation.
Designed for casement windows which are 20" to 32" wide and up to 72" high, with a 73 pound sash weight.
Patented dual arm action pushes the sash open while pulling the hinge side of the sash to the open position. When properly installed this operator results in almost effortless operation of both casement and awning-type windows of many sizes and weights.
