The Mortise Lock
Traditional wooden doors, both internal and external feature mortice locks. Mortise locks are embedded into the door for added strength and provide a locking point in the door’s centre, making them amongst the most secure types of domestic hardware currently available. A pocket is cut into the short edge of the door, allowing a longer and thicker mortise box to slide into the door itself, giving superior security, which is why mortise locks are so much more secure than their cylinder counterparts. The door is securely locked when the bolt is in the mortice. Mortise locks are a great way to strengthen any sort of lock so that residences or places of business are better protected.
A mortise deadlock is designed to be fitted into the timber edge of a door and allows the door to be manually locked from both sides with a key. A deadlock is a lock bolt only and does not have a latch/catch section for the operation of a door knob/handle. These types of locks are available as either 3 or 5 levers. The security benefit of a deadlock is that it can be locked from the inside as well as out, so if an intruder gets into your house through a window, they can’t leave through the door with the deadlock on it.
The Chubb Lock
Chubb lock is a lever tumbler lock that is well-liked by people who want to increase the security of their homes, offices, or other public places. Chubb is the most widely used manufacturer of mortice locks in the UK, which explains why they are frequently referred to as Chubb Locks. Chubb locks operate similarly to cylinder locks, but rather than using pins and springs, a set of levers must be raised in order for the bolt to travel into or out of the door frame.
