Hinge locking makes levering out of the door so much more difficult thus providing additional anti-burglar protection.
The integrated closing bow provides a further locking point on the lock side of the door. When the door is opened it runs against the closing bow. In this position it is possible to talk to someone outside whilst the door is secured. The locking parts which are completely hidden can be released when the door is unlocked from outside or the door handle on the inside is activated.
The closing bow is available with the 3 point claw locking with 2 swivel bolts.
