  • TBT function for window handles
  • TBT function

    As well as the existing lockable tilt and turn window handle there is also the so-called TBT window handle for windows with a TBT mechanism.

    TBT (Tilt Before Turn) describes the type of opening sequence: Lock position, tilt position and turn position.

    The TBT window handle tilts the window by turning the handle to the horizontal position - without having to unlock the locking cylinder. The locking cylinder has to be unlocked before the handle can be turned to the unlocked position (pointing upwards).

    TBT window handles can only be fully opened using the locking function. This prevents TBT windows from being unintentionally opened from the inside by children, for example.

    This is how it works:

    The Paris E138Z/US950S TBT4 (100 Nm) model can be locked with the key in the 0° locking position, and therefore has an additional forced entry resistant security function.

    The handle can be operated again in the unlocked condition.

    The unlocked handle can be turned to the 90° tilted position (without operating the key). The handle's 180° position can only be reached by simultaneously operating the key and continuing to turn the handle.

    The window handle is automatically locked (without operating the key) when the window is closed.

    (1) Locked position = 0°

    (2)Tilted position = locking cylinder locked 90°

    (3)Turn position = locking cylinder unlocked 180°


    The TBT function is only provided if a tilt and turn fitting, that is intended for this purpose, is used.
