The unique climbing T-LOK Roller Coaster makes it possible for curtains to move up and down over slopes and arches. Modern architecture very often deviates from classical right angles and horizontal ceiling lines. This calls for curtain rails that follow the resulting contours and enable electrically operated curtains. T-LOK RollerCoaster, the self-propelled and climbing curtain drive, was developed for this purpose.

If blackout curtains, acoustic curtains or decorative curtains are not only to be opened and closed horizontally, but also to overcome height differences via slopes and/or radii, then the TT2 curtain traction system with the climbing T-LOK RollerCoaster electric drive is the world's only means of achieving this as standard.
Curtain drive T-LOK RollerCoaster overcomes radii from 35 cm upwards, downwards and of course laterally.
Even over vertical distances, curtains can be opened and closed with the TT2 curtain system with the climbing curtain drive T-LOK Roller Coaster.
These unique characteristics offer creatives such as architects or stage designers previously unimagined possibilities for moving fabrics and curtains.
