Product Overview

The ADI BLOCKLOK 444DD DBLE SC is a heavy-duty locking solution designed to secure double-door shopfronts, commercial premises, warehouses, storage facilities, and other applications requiring high-security door locking. This rear-fixing model is suitable for aluminium and timber doors and is commonly used on hinged, sliding, and swinging doors.
