Product Overview

The ADI BLOCKLOK 444DDFM BLK DOUBLE FRONT MOUNT is a heavy-duty security lock designed to secure double-door shopfronts, commercial premises, warehouses, and other high-security applications. This front-fixing model is suitable for aluminium and timber doors and can be installed on hinged, sliding, and swinging door types.

Finished in black, the lock features a 13mm hardened steel locking bolt that offers excellent resistance against forced entry. The locking bolt is retained when unlocked to prevent loss or damage during operation. It uses the industry-standard 570 oval cylinder, making it compatible with most restricted key and master key systems.

Manufactured in Australia, the ADI BLOCKLOK 444DDFM BLK is supplied complete with a mounting template and fixing hardware.
