With the plug door SST, FBT made a mark! The system is proven and shows all typical characteristics of an FBT door:
Reliability, robustness, durability and minimum maintenance at a fair price! As a result of the well-designed construction, the door protrudes minimally when open and doesn’t cause any inconvenience in the passenger zone when closed. Another advantage: Since no cutout in the roof frame is required, the drive remains unaffected when the door wings are open.
