Three equally spaced 2″ x 4″ x ~=10.75′ cross members are placed on and perpendicular to three similarly spaced 4″ x 4″ x ~=10.5′ runners. A corrugated door is then placed face up on the cross members. Three 1″ x 4″ x ~=10.75′ spacers are placed between each door to keep them from coming into contact with one another. A total of 12 boards are used for this purpose. Three 1″ x 4″ x ~= 10.5′ boards are equally spaced and placed over the top door in order to provide protection from the three 1.25″ non-metallic bands used to secure the package.
