For some time now patio doors have been vulnerable to lift attacks, a method whereby the sliding door is lifted out of it’s track and allowing access to a property.
As featured on Dragons Den, the anti lift device has a very simple locking method, the spring loaded bolt is withdrawn by simply pulling the large black knob, when fully retracted the knob can be twisted left or right to hold the pin in the open position. When retracted the Ivess lock pin is an extra 1.5cm further out than normal, this allows for an easy visual check to make sure the patio door is secure.
Secure ventilation can also be achieved with the Ivess lock, by the addition of a second hole for the locking pin slightly further along the door sill. With a second hole, the lock can be used to hold the door in a slightly open position, allowing good ventilation but restricting the door to be opened further, this is great protection for pets and children.
This patio door lock is not locked with the use of a key, where this function allows for easy use, it could also allow an easy exit point for an intruder who made entry via another door or window.
