5 Lever British Standard Deadlock – Stainless Steel Satin (78mm Case / 57mm Backset)
A high security mortice deadlock for internal and external doors in both commercial and domestic buildings. The 5 lever mechanism and British Standard certification provide insurance-approved security, while the satin stainless steel finish offers a modern, corrosion-resistant appearance that complements contemporary door and hardware styles.
Key Features
- 5 lever mortice deadlock providing enhanced protection against picking and forced entry.
- Tested to BS 3621:2007 for insurance-approved security on external doors.
- Anti-saw and anti-drill features on the bolt and lock case to help resist common forms of attack.
- 20mm deadbolt throw for secure locking engagement into the frame.
- 57mm backset – ideal for doors with existing deeper lock mortices or where additional handle/escutcheon clearance is required.
- 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.
- Can be fitted to left- or right-handed timber doors.
- Supplied complete with 2 keys, strike plate/keep and fixing screws.
Typical Applications
- Front and back doors in domestic properties where BS 3621 deadlocks are required by insurers.
- Entrance and exit doors in commercial premises, offices and retail units.
- Upgrading older or non-compliant deadlocks to meet current British Standard security requirements.
- Refurbishment and new-build projects needing a robust, insurance-compliant deadlock with a modern aesthetic.
- Properties in coastal, urban or damp environments where added corrosion resistance is beneficial.
