The concept arose due to many houses in London having to retain their traditional timber front doors due to conservation zones. Most door are fitted with a BS3621 approved mortice deadlock but householders are not locking this when they leave the property allowing thieves the easy task of breaking in through a Yale type lock.

The Finfort concept was inspired by the operation of the Ingersoll SC71 Cylinder Rim Automatic Deadlock. The auxiliary bolt is depressed by contact with the strike plate to shoot the deadbolt into the bolt hole automatically deadlocking a door without the need for a key. One may think it necessary to use two keys simultaneously to unlock the Fin lock and a night latch but the unique operation of the Finfort lock retains the deadbolt in the unlocked state until the mechanism is reset by opening the door allowing separate operation of each lock, as can be seen in the video.

Refurbishment of Victorian rebated mortice latches and manufacturing new latches for an iconic London institution

AMTLS were approached by an iconic London Institute to refurbish Victorian rebated mortice latches.

The project involved sensitive restoration and detailed knowledge to carry out the refurbishment, and avoided our customer having to replace these attractive and practical Victorian lock sets.

AMTLS were recently commissioned to assist with large, old Chubb Deadlocks. These characterful locks required cleaning and restoring to give a consistently reliable action.

In addition, AMTLS cut and provided new keys.
