Enginuity, from Caldwell Manufacturing, is a patented system for hung or slider windows and patio doors that features a sleek, concealed design that fits completely in the top track of the patio door. The Enginuity patented system can also be nestled in the side jamb or a compact design attached to the lift rail of the hung window. The Enginuity actuator can be on either side and adapted to any desired travel length, from 4 inches or less to fully open.
