The perfectly matched components of the security door locking system are as solid as they look. Hallmarked by lifelong function and supreme security. Solid components and precise manufacture ensure readily available locking mechanisms and hence guarantee the best locking force possible, enough to deter almost every kind of tool a burglar might use. Its flexible modular structure permits problem-free adaptation to and installation in all kinds of exterior doors made of wood, PVC-U or metal. The type of locking system and number of additional locking points can be selected individually depending on what kind of protection is required and the potential hazard.
Hook with rear claw
Not only does the stable steel hook engage deeply in the keep rail in locking position, but the keep rail locks in the frame at the same time. This helps to provide extra security by preventing the door sash from being ripped from the door frame.
Actively secured lock technology
Very robust sintered metal gearwheels guarantee long-term reliability. When bolted, the lock mechanism is blocked. The hooks are blocked securely and cannot be compressed either individually or together. The lock mechanism can therefore only be unblocked using the appropriate key and optionally unlocked by means of the locking cylinder or by actuating the handle.
Main deadbolt made of steel
Main deadbolts made of steel lend the Winkhaus security door locking system supreme strength even in the door’s mid-range.
Contact pressure adjustment
Together with the conically shaped hook, contact pressure adjustment in the keep and keep rail ensure good locking at all times. This permits door system tolerances to be adjusted with precision and evened out.
Continuous frame keep sets
Load forces are distributed equally over the entire frame rail without interruption. The enormous stability offered can be seen even by laymen. As far as professionals are concerned, “continuous” also means simple, convenient fitting.
Easy key insertion
The mechanical structure of security door locking devices ensures that no forces stress the cam when the door is bolted. This permits the key to be inserted without problems in the locking cylinder at any time
