TOP 2000 twin
TOP 2000 twin single and double leaf doors, with windows, sidelight and fanlight as well, are tested Class 4 anti-burglary resistant according to EN 1627:2011 norm.
EXCLUSIVE LOCKING SYSTEM VIGHI’S APPLIED TO TOP DOORS
The deadbolts do not come out from the lock, but they are distributed along the bar of the leaf and are self-locking.
The twin models have a secondary lock.
When the door is closed for the main lock, turning the key of the secondary lock, the cylinder stops rotation of the main lock key, which controls the deadbolts.
This is a useful solution for preventing, if necessary, access to the people who hold the key of the main lock.
