Delivery detailsA high security mortice deadlock for interior and exterior doors in commercial and domestic environments. Tested to BS 3621:2007 and CE marked to BS EN 12209, it provides insurance-approved protection for external doors, while the satin stainless steel finish delivers a modern, corrosion-resistant appearance that complements contemporary door hardware.
Key Features
- 5 lever mortice deadlock offering strong resistance to picking and forced entry.
- Rigorously tested to BS 3621:2007 – commonly required by home and contents insurance policies.
- CE marked to BS EN 12209 and Certifire approved for use on 30 & 60 minute fire doors.
- Anti-drill protection on the lock case to help resist common forms of attack.
- 20mm steel deadbolt throw for secure engagement into the door frame.
- 78mm case with 57mm backset – ideal for deeper lock mortices and where extra clearance around handles/escutcheons is needed.
- Satin stainless steel faceplate and keep for a durable, corrosion-resistant, contemporary finish.
- Suitable for use with standard mortice deadlock escutcheons where a separate latch is not required.
- Supplied with 2 keys, Euro profile keyhole escutcheons, escutcheon cover, strike plate and fixing screws.
Typical Applications
- Front and back doors in domestic properties where BS 3621 deadlocks are required by insurers.

- Upgrading older or non-compliant deadlocks to meet current British Standard security requirements.
