1. What Is a Five-Lever Mortice Deadlock? 🔑

A five-lever mortice deadlock is a robust locking mechanism commonly installed within wooden doors. The term “mortice” refers to the lock being fitted into a cavity within the door itself, rather than being surface-mounted. The “five-lever” aspect indicates the presence of five levers inside the lock, which must align correctly when the key is turned to retract or extend the bolt. This design offers enhanced security compared to locks with fewer levers.Door Handle Store
