The Chubb 4L67E's hardened steel 18mm deadbolt automatically deadlocks on closing the door, providing convenience with high security.
High security features in the design include drill, saw, pick and torque resistance and an internal lockable handle. This makes the 20mm Chubb rim lock ideal for all types of front doors in particular glazed doors, as the lockable handle cannot be operated through a smashed window.
