End sections are approximately 4½ feed wide and 40 feet long; intermediate sections are approximately 9 feet wide and 40 feet long. Width is the distance between frame arches, with an allowance for a 6-inch overlap. Length is the curve of the arches. Each end section contains a vehicle door, a personnel door, a ventilator, and two heater ducts. Each intermediate section con- tains a plastic window, screen, and blackout flap. d. Tent Liner.
