Lockwood 355 Double Cylinder Deadlock – The Heavyweight Champion of Rim Locks
If the Lockwood 303 is the industry standard, the Lockwood 355 Double Cylinder Deadlock is the undisputed heavyweight champion. At Aus Lock and Safe Co, when a customer asks for the most "tank-like" rim lock available for a timber door, this is the one we pull off the shelf.
It is arguably the most famous deadlock in Australia, known for its unique interlocking strike and case that practically fuses the door to the frame. For Melbourne homes with high-value assets or those in high-risk areas, the 355 is the ultimate peace-of-mind upgrade.
Why the "355" is the Insurance Favorite
Most insurance companies in Australia look for "double cylinder" protection on external doors. The Lockwood 355 doesn't just meet that requirement; it exceeds it. Because it is a Double Cylinder lock, it requires a key to lock or unlock from both sides. If an intruder smashes a glass side-lite to reach in, they will find the internal knob is deadlocked, preventing them from opening the door and walking out with your belongings.
