ShutterTop is the new security lock for metal frames designed by ISEO for railings, shutters and gates, and offers high safety standards thanks to the combination of multiple patented technical solutions.

The peculiarity of the lock lies in the fact that it is equipped with:

• two independent rotating deadbolts,
• an innovative patented trap system which makes the lock resistant to any attempts to lift the bolts.

The bolts have a patented trap system that makes break-in attempts considerably more difficult and time-consuming.

The break-in attempt must be made on both bolts one by one and, moreover, when a lifting load is applied to one of the bolts, when the threshold value of 100 kg is reached, the rotation fulcrum of the bolt breaks in a programmed failure, effectively locking the bolt in its housing on the face plate.

Thus, locked in the secured position, the dead bolt can no longer be retracted inside the lock case, thus making the break-in attempt fail.
