The window's shut – guaranteed! With ABUS window handle locks.

Shut the window – and it's locked! That's how easy lockable window handles are to use. It's impossible to forget to lock them ever again. You just need a key to unlock the window handle lock.

The police and insurance companies recommend such user-friendly additional locks for window security.

ABUS FO400 and FO500

A solid, adjustable steel bolt ensures that the FO400 can withstand a load of more than a tonne. The special design of the lockable window handle means that it can also be fitted to extremely narrow frames. Even with windows that are very soft, the typical claw action of the window handle lock provides an extremely high level of security.

With just a single bolting action, the FO500 lockable window handle closes and secures the window. When it is in the locked position, the solid swivel bolt engages with the lock casing that is firmly attached to the window frame. In addition, the catch integrated into the window handle lock provides extra protection when the window is in the tilt position.

It has received the approval of the VdS (VdS Schadenverhütung GmbH under the umbrella of the Association of German Insurers (Gesamtverband der Deutschen Versicherungswirtschaft e.V. [GDV]).
