The No 9496 sash lock is meant to secure double hung windows which are too high to reach. The loop in the latch handle allows a pole and hook (see the No 9581 transom hook) to engage or disengage the latch. A leaf spring holds the latch handle in horizontal or vertical position. Overall dimensions of the base are 1-3/4″ x 2-1/4”. The handle measures 3″ long from pivot point to end. All Nanz finishes are available.
