19 Series Positive Action Lock (PAL) System
Truth's Positive Action Lock (PAL) Systems are some of the most versatile and easy to operate locking systems in the marketplace today. A simple movement of the locking tab disengages the lock allowing the sash to move freely. When the window is closed the PAL System automatically locks, securing the window without having to manipulate the lock again. These locks can be used with or without a keeper depending upon the window's design and the lock style.
