Lockable Window Handles

HEWI window handles for locking enable windows to be opened only with a key. In addition, optional lockable window handles with a tilt-before-turn function are available. If the window handle is locked, when turned through 90° it releases the window for tilting.

The window leaf cannot be completely opened (turned) in a closed function. The lockable window handles are certified by an independent test institute. They fulfil the requirements of resistance class RC 1-6 (protection against twisting off and forced lock-snapping).
