Double Locking Protection

The double locking mechanism provides two independent locking points, making your door significantly more resistant to forced entry compared to single-latch locks. This dual-point security means potential intruders face twice the challenge, dramatically improving your home or business protection.

4-Pin High Security

The 4-pin mechanism provides enhanced security over standard 2-pin locks. More pins mean more possible key combinations, making unauthorized duplication more difficult and pick-resistance significantly higher. This is the security upgrade that makes a real difference.

50mm Standard Backset

The 50mm backset is a standard measurement that fits most door preparations, making this lock a direct replacement for existing 50mm backset locks without requiring door modification. This standard sizing ensures compatibility with most doors and handles.

Flexible Cylinder Options

Standard cylinder included with three keys for a convenient installation. 

Perfect for entrance doors, office doors, commercial properties, and any application requiring high-security protection with double locking mechanism. Complete with striker plate and fixing screws.
