Key Features

• Winkhaus is a market leader in producing innovative security solutions to meet the changing security and ease-of-use requirements.
• The Winkhaus autoLock AV4 is an slam shut multi-point locking system that when the door is closed, the security hooks are triggered by a magnetic release located in the centre keep, securing the door.
• The magnetic release, activates the locking mechanism and thereby prevents damage to the door frame and minimises the locking sound when in operation.
• Optional daytime latch integrated into the keep enables temporary flexible entry and exit without the use of a key.
• Option to be paired with electronic features and access controls.

Innovative hook design

The new hook design have brought added benefits to the AV4 including:

• Non-Handed - The locks are no longer handed and the striker latch can be easily reversed.
• Increased installation tolerance - reducing the need to adjust the lock during the life ofthe door, saving time and money.
• 40% Lower Operational Forces - The new hook profile reduces friction against the keep, making it easier to unlock the door using a key / thumbturn.
