Tilt-First Handles – Tilt before Turn
TBT window handles enable the "Tilt Before Turn" principle. This means the window can first be tilted for ventilation, while full opening via the turn position can be controlled or restricted. Lockable TBT window handles are particularly suitable for areas where windows are to be used for ventilation, but unauthorized full opening is to be prevented.
What does TBT mean for window handles?
TBT stands for "Tilt Before Turn". In contrast to the usual turn-tilt operation, a corresponding TBT system first enables the tilt function of the window. Full turn opening can be controlled or only used after appropriate release, depending on the handle and hardware system used.
