Sliding doors are a popular feature in Australian homes, units and apartments, but they’re only as secure as the lock fitted to them. At Lockmart, we stock a carefully selected range of sliding door locks designed for timber, aluminium and glass sliding doors commonly used in residential properties across Australia.
Whether you’re replacing a worn lock, matching an existing setup, or upgrading for better security, our range includes mortice sliding door locks and compatible locking hardware from trusted Australian brands, suitable for everyday use in homes and rentals.
Choosing the Right Sliding Door Lock
Sliding door locks differ from standard hinged door locks and must be matched correctly to the door type and cut-out. Many older sliding doors suffer from worn latches, loose snibs or poor engagement, which can compromise security over time.
When selecting a sliding door lock, it’s important to consider:
-
Door material and profile
-
Backset and cut-out compatibility
-
Internal snib vs key operation
-
Replacement vs new installation
-
Upgrade options for improved security
Our range focuses on locks that are commonly used, easy to service, and proven in real-world installations, not obscure or discontinued models.
