Telescoping Doors The special drive system on the 5200 and 5300 Series synchronizes the moving panels so the faster-moving outer panel and slower inner panel reach the jamb at the same time. The 5200/5300 Series door creates a greater clear door opening width while offering the same performance and safety features of our 2000/3000 Series sliding doors.
Bypass Door By keeping the entry and exit doors independent, the ByPass system allows for increased and controlled pedestrian traffic flow.
