What is a bi-fold door?
Most transit buses use a bi-fold door (rather than sedan doors) which means two doors in one that separate to permit entry and exit. An over the road coach has a salon door or cafe style door that swings on one side and opens at a 45 angle. The better door is the salon door because you’re only dealing with one set of seals that are pulled in tight to the bus as the door locks. On a bi-fold door, the door doesn’t pull in as tight. This system is designed for many, many thousands of openings and closings, so they have a tendency to wear the heavy rubber seals down and they always have air leaks. We are designing a stainless steel kit door to replace the bi-fold door on MCIs. Call and ask about scheduling.
