90% of all residential break-ins occur through windows that have inadvertently been left unlocked. The Milgard lock's lever is up when the window is unlocked, down when it is locked. This allows the homeowner to scan the house quickly and feel confident about home security. In a new approach, the lock mechanism is integrated with the window structure itself with an intuitive operation: To open the window, lift up on the lock; to open a window to the right, push the lock to the right. Its ease-of-use makes SmartTouch a natural choice for an aging population.
