With young children in the home, you know all too well how hard it is to keep an eye on them at all times. With the Cal Double Bolt child proof patio door lock installed, you can make sure that young ones do not become tempted to open the sliding glass doors on their own and expose themselves to potential danger. The Sliding Glass Door is one of the favorite "break out" spots for children. The closing mechanism is usually a latch, not a lock. This means that it is easier for children to operate than it is for adults to secure. Simply mount the Cal Double Bolt at a height that is unreachable by your children. Another advantage of the Cal Double Bolt sliding door lock is that it is clearly visible whether the lock is engaged or not, so it is more likely that parents will keep it in the locked position. The CAL Double Bolt Lock has a sleek, aesthetic, low profile design. As a result, the sliding glass door lock fits easily within the limited space available between the sliding glass door frame and the interior of the door panel. This amazingly simple device is EASY TO INSTALL and has been tested to provide over 1000 lbs of Forced Entry Load Tension. The Cal Double Bolt patio door lock prevents criminals from being able to lift out sliding glass doors from their tracks. Most factory installed locks or after-market products do not. Criminals know how easy it is to lift a door panel out of its track. Great for parents, grandparents, day care centers, and more. Premium quality metal materials No parts or keys to lose like other locks Black Color Additional Details ------------------------------ Product description: With young children in the home, you know all too well how hard it is to keep an eye on them at all times.
