How many tracks do two-speed, center-opening doors have?

Two-speed, center-opening doors typically have two tracks. Each door panel operates along its own track, enabling them to open from the center towards the sides. This design allows for a wider opening than traditional single-leaf doors, facilitating easier access for passengers and wheelchairs. The two-track system is essential for the smooth operation and alignment of the doors as they slide open and close.

In contrast, misunderstanding the number of required tracks can lead to installation challenges, as tracks must be properly aligned to ensure functionality. Options that suggest a different number of tracks overlook the mechanical requirements for the dual-panel system to operate effectively.
