SABS MOTION is a device that provides automatic, safe braking in the closing direction and offers no resistance in the opening direction. The unique slow down mechanism of SABS MOTION controls the movement of the Acoustic Slider and is easily incorporated into building designs to achieve full DDA compliance.

SABS MOTION uses patent pending technology to provide sliding resistance between the door and the track in the closing direction only and unlike other systems, Lotus SABS MOTION is all contained in the head track, not the floor track, eliminating any potential to jamb. SABS MOTION uses a unique rotary damper and gearbox mechanism attached to the door to engage with a rack gear inside the track. The mechanism is designed to automatically engage in the closing direction to slow the door, and automatically disengage to provide no resistance when opening the door.
