Eclipse BS3621 5 Lever Mortice Deadlock Satin Chrome 63mm

The Eclipse BS3621 5 Lever Mortice Deadlock in a satin chrome finish delivers compact, insurance-approved security for external doors. Certified to BS3621 British Standard, this deadlock is ideal for properties requiring a high level of protection, especially where a smaller 63mm case size is needed for slimmer timber doors.

Built with a robust 5-lever deadlocking mechanism, it provides strong resistance to picking and forced entry. The deadlock-only operation is key-controlled from both sides, making it an excellent choice as a primary security lock or as a secondary lock used alongside a night latch or sash lock. The satin chrome faceplate and escutcheons offer a clean, modern look that pairs perfectly with contemporary door furniture.

Supplied as a complete set with keys and fixings, this lock combines certified security with dependable performance in a compact format.
