The CRL Security Bar Lock for sliding glass doors helps prevent forced entry through sliding glass doors. It has telescopic adjustability to accommodate 28" to 48" (711 mm to 1.22 m) wide sliding patio doors. Made from two square extruded aluminum tubes, one sliding inside of the other, and a locking collar to lock the bar's length once it has been adjusted to match the width of the door.
