Simple to use, Inexpensive, VERY Secure! The Engert Slide-bolt locks many types of doors, windows and gates from the inside.
The secret is the loop! The weight of the metal loop keeps the slide-lock in the 'lock' or 'unlock' position and it cannot be vibrated or bumped. Positive locking, protected from outside attack, yet easy to lock and unlock.
Price is for (1) slide bolt, but (2) strikes are included with each single package for universal mounting options.
Tip: Mount the slide-bolt high on the door and jamb to keep the toddlers from wandering through the door or gate.
