Blocklok
ADI Blocklok Locks, commonly known as Block Locks, are a popular high-security locking solution used to secure shopfronts, sliding doors, gates, warehouses, and commercial entry doors. Manufactured in Australia, they are trusted by locksmiths and property managers for their strength, reliability, and ease of installation.
Available in single and double locking models with front-fix and rear-fix options, ADI Blocklok locks suit aluminium, timber, and steel door applications. Each lock features a hardened steel locking bolt and uses the industry-standard 570 oval cylinder, making it compatible with most restricted key systems.
