Adding a FinBolt is an easy security upgrade to automatic deadlocking.

High security no longer means clunky or ugly.

The compact FinBolt lock comes in standard sizes to fit the vast majority of wooden doors.

The FinBolt has sleek & elegant lockguards that suit both period and modern wooden doors.

Why we created it

We believe everyone should have the choice of beautiful high-security door locks that do justice to the discerning homes they secure.  We are passionate about providing beautiful, convenient, high-security door locking solutions that make a great first impression. 

We created the FinBolt after years of being dissatisfied with traditional locks that require users to stop and lock.  The fact is most people don’t have time to lock their doors properly which unfortunately leaves them vulnerable to opportunist burglary.  FinBolt co-founder Hilary Duggan fell foul of just this when she walked in on a burglar in her home in London. This experience has driven her passion to find a better way to keep our homes secure.

After several years of design, prototyping, patenting and testing, the FinBolt lock is unlike any other. It combines elegant design with award-winning engineering to secure your home automatically, without ever having to turn a key. The thumbturn mechanism ensures you can always get out fast when you need to so you can enjoy safer, automated door security that never compromises on style.

The FinBolt is an easy upgrade to automatic deadbolting which complements your existing British Standard 3621 (BS3621) door locks.

Frequently Asked Questions

'Just one lock on a door isn’t enough. Burglars can use their foot to check whether there is a dead lock on the door. If the door moves more than two millimetres, they will immediately know that your door isn’t double locked, giving them easier access to your property.’ Former burglar turned security expert Michael Fraser

A latch is a passive form of locking a door, It is only meant to act as keeping the door closed and to stop people just walking in. A burglar can slip a latch in less than 30 seconds.  See how they do it.

By deadbolting automatically, the FinBolt greatly reduces the risk of burglary as the door is always deadbolted when closed.  It only takes one occasion to forget to manually deadbolt your door to become an easy target for an opportunist thief.  Our customers tell us that knowing their doors are always deadbolted just by closing them is incredibly reassuring and that they could never go back to manual deadbolting. 

The FinBolt combines two unique ideas: a connected trigger & bolt action that automatically deadbolts your door every time you close it and, a holdback function so that when you unlock the FinBolt, it stays temporarily unlocked for your convenience, allowing you to remove the key to open any other locks on the door.  The action of closing the door will retrigger the deadbolt automatically every time

A FinBolt can be added to your door alongside your existing locks, delivering all the functionality of automatic deadbolting.  Alternatively, you can choose the FinBolt dual or triple door sets which are  BS3621 insurance compliant and are made up of either 2 or 3 door locks that use identical Avocet ABS 3 star TS2007 cylinders so one key opens all locks (say goodbye to your heavy bunch of keys!)

If you are looking for high security locks for an existing door and you already have at least one British Standard 3621 lock (BS3621), then we recommend you keep your existing locks and add The FinBolt which is an easy upgrade to automatic deadbolting and comes in a choice of size and finish to match your existing locks and door furniture (letter box, knocker etc).

If you are looking for locks for an existing door but do not have at least one BS3621 lock now OR if you are replacing your door, then we recommend FinBolt Dual Door Set which is a beautifully matching high-security, BS3621 insurance compliant door set that automatically deadbolts your door with a 21mm automatic deadbolt and also has a manual deadbolt which you can choose when to you.

If you are looking for locks for a new door which will be clearly visible from the street in a busy, built-up area then we recommend FinBolt Triple Door Set which is a beautifully matching, BS3621 insurance compliant door set that simultaneously deadbolts at two points on your door with two 21mm automatic deadbolts for the most convenient high security and also includes a manual deadbolt which you can choose when to you.  

The FinBolt is a BS8621 door lock with thumbturn cylinder as we believe homeowners should always be able to get out of their home fast in case of fire or any other emergency.  A FinBolt can be added to doors with an existing BS3621 night latch or mortised BS3621 deadbolt therefore the door will remain insurance compliant.  FinBolt dual and triple door sets are BS3621 insurance compliant as the door set is a mix of BS8621 FinBolt & BS3621 kitemarked manual deadbolt locks

Polished brass and chrome are the standard finishes as these complement the majority of existing door locks that the FinBolt may be added to.  However, other bespoke finishes like satin chrome, antique brass and bronze are available as a special order.  If you have something particular in mind, get in touch at contact@finfort.co.uk to discuss

The security of a lock can't be determined visually, so physical assessments are carried out to evaluate the lock's security by rigorously testing wear and tear over time and replicating the most commonplace methods of compromising the lock. The standards for locks are produced by the British Standards Institution (BSI). A lock that conforms to the required British Standards will display the numbers of the standards it has passed. The most common domestic locks will usually show BS3621 or BS8621.

To check if your locks are British Standard, look out for the British Standard Kite Mark or the British Standard number BS3621. We've included photos of two common domestic locks (Mortise Locks and Night Latches) to help you identify which locks you have and where the kite mark can be found.
