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.
COLOURS AND GLAZING
Our aluminium profiles are polyester powder coated by our systems suppliers using the very latest paint application techniques guaranteed for 25 years.
Fully compliant to the latest June 2022 building regulations our standard double glazing is the exceptional light transmitting, energy saving ClimaGuard® A+ low emissivity (Low-E) glass manufactured by Guardian Glass.
