Sealing Aircraft Tail Dock Doors

Aircraft tail doors are used in hangars when it is not economically feasible or practical to make the main doors full height. Normally, these doors are used when the facility is dedicated to one aircraft. vertical lift, rolling shutter (coiling) or jamb guide canopy are the normal choices for a tail door system. If the tail door slot width is small and less than forty percent of the main door (in the closed position) is being cantilevered into the tail opening then the natural choice is a rolling shutter (coiling) type door. However, if the tail slot width requires more than forty percent of the main door to cantilever into that area, a jamb guide canopy is used because it can structurally carry the top guides for the main doors.
