Sliding door security
Sliding door locks
Sliding doors in houses are an efficient way to have a large opening space while minimizing the door opening footprint. Al sliding door can either slide into a wall cavity or slide parallel to a fixed door panel. Glass sliding doors are a good way to extend the inside of a house with an outdoor patio or deck.
Most glass sliding doors come installed with a lockable catch in the centre of the door which hooks into a strike plate on the opposite door frame or opposite door in the case of twin sliding doors.
Sliding door latch
The standard lock supplied from most manufacturers is a very basic latch. These latches have some vulnerable weak spots which make them easy to force open or easy to manipulate from the outside of a door. Some latches are even made from plastic which can get brittle as it gets older. A better quality lock installed in the centre of the door is a good place to start when you are trying to make a glass sliding door harder to break into. There are locks available with much stronger bolts then the standard parrot hook design. Many locks will lock into the strike at the top and bottom to ensure the door can not be jiggled open or manipulated from the outside. The strikes should also be made of a steel construction to resist forces from jimmying. The strike should also be able to be screwed in securely using multiple screws.
Lockable Bolts for slidng doors
Lockable bolts fitted to the inside of a sliding door add extra security and physical strength against a forced attack. A bolt with a key ensures the bolt will stay in the locked position if the door is shaken up and down or if the glass is broken to lift the bolt up. A locksmith should be consulted to the best placement of the lockable bolt. Bolts fitted to the back edge of the door are usually preferred as the screws are not taking as much of the force if the door has extreme pressure placed on it. A lockable bolt with large diameter bolt, a strong lock body and extra fixing points is a good place to start when choosing a patio bolt that will withstand an attack.
