Peace of mind premium security

A tough multi-point locking mechanism protected with the Avocet ABS euro cylinder further enhances the appeal of this elegant bi fold door manufactured to our usual industry leading high standards.

The clever locking system of the Avocet ABS® diamond grade cylinder knows when it has been snap attacked and fires into action to create a robust barrier to entry. The patented Active Cam TechnologyTM is hidden deep within a solid Molybdenum cam which is 20% stronger than steel, and delivers ultimate resistance against a lock snapping attack and snap/twist manipulation. All of the snap technology is focused on the outside part of the lock only. This makes sure that maximum strength is given to the inner part of the lock - the part that has the job of securing your door.

The guys did an excellent job today removing my old doors and then installing my new bi-folds... old doors and frame out cleanly and then installed the new doors very neatly. All in all an excellent job well done. The new bi-fold doors look really good!
