Bottom or Side Latch Replacement:
Each exit latch is attached to the window frame using two small screws and nuts. Remove these with a suitable Phillips head screwdriver and a small wrench. Discard the defective latch. Some windows include a metal stiffener bracket on the back of the latch and frame. These must be re-used with the new latches. Place the new latch into position and align the holes of the latch, frame and stiffener. Secure the new latch with the screws provided. Check for ease of opening and secure closure.
