Floating Group Slide Doors

These doors have leaves that are connected to each other, but are not attached to the building in any way, and can open from either direction and moves as a group abreast of each other. United Airlines' spacious maintenance hangar has two identical and opposite door openings 250'-0" wide by 71'-0" high. Each opening is filled by two (2) sets of outside mounted 3-leaf motor-operated Series 500 floating group hangar doors.
