Visofold Series Product Data Sheet – IMS104DVS.201410

Many thanks for supplying and installing my new bi-fold doors. The guys did an excellent job today removing my old doors and then installing my new bi-fold doors. They managed to get the 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!

Premium Security Fitted As Standard With Patented Active Cam Technology

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.
