Sliding Security Barrier Door Lock Black + Cylinder

The Tradebase Sliding Security Door Lock – Keyed is a reliable replacement solution for sliding security and screen doors originally fitted with Austral® TD7 and Gainsborough® style locks.

Designed for everyday residential use, this lock features a self-latching bolt that automatically engages when the door is closed. The supplied 4-pin cylinder allows the lock to be deadlocked or unlocked from either side using a key, while the internal snib provides convenient locking from inside. The key overrides the snib for added safety.

An anti-lift pin integrated into the striker plate helps prevent the door from being lifted out of its track. The lock is universal and reversible, making it suitable for left- or right-hand door configurations. Upgradeable to a triple lock . Finished in black for durability and corrosion resistance.
