Deadlocks for added security in Adelaide


In order to boost security a deadlock is well worth installing. Deadlocks have a higher level of protection than the pin tumbler lock which is commonly used and much easier to break into.

Secure Strong Steel Deadlocks


The higher security of a deadlock is obtained by having a strong steel bolt that extends into the door jamb and strike plate of a door.

• Single cylinder deadlock which uses key to open the lock from the inside or outside
• Double cylinder deadlock which uses a key on the outside but a twist knob on the inside

The single cylinder deadlock system can be venerable to a breaking through a window allowing an easy exit through twisting the knob on the inside, whereas a double cylinder deadlock can avoid this.

Deadbolts can also be selected to match the decor of your home, often having a variety of styles, looks and colours that can complement the security of your door.
