Automatically Double Locks
In addition to being strong and simple to use, Finfort believes that the best front door lock security is automatic.
The patented mechanism is our automatic deadbolt works alongside any nightlatch to automatically ‘double lock’ a door at 2 points as it closes.
As the door closes, a 21mm deadbolt automatically engages—offering unmatched security beyond standard front door locks. Locks can be opened, one after the other, with one hand.
Finfort automatic deadbolt locks are the most secure and versatile deadbolt locks available: they suit front or back doors, can replace a 5 lever mortice deadlock or can be added to the middle or bottom of any wooden external door and work alongside existing locks.

Unique Patented Mechanism
As the door closes, a 21mm deadbolt automatically engages. The lock's unique internal configuration means that all locks can be opened, one after the other, with one hand.

Works With Existing Locks
On this grey door, a single automatic deadbolt lock is fitted at the bottom of the door and works with the existing nightlatch to automatically ‘double lock’ the door at 2 points.

Ideal for Urban Areas
In our Triple Door Lock Set, the automatic deadbolt works in tandem with the auto-deadbolt nightlatch to automatically bolt the top and bottom of the door every time.
