(1) Arch Assembly. The arch assembly consists of two
aluminum side arch assemblies and an aluminum roof arch assembly.
The arch assembly can easily be folded into a closed “W”
configuration for easy handling and transport. A non-
sectionalized arch assembly and a sectionalized arch assembly are
currently fielded. The difference between both types is that the
sectionalized arch assembly consists of two interlocking pieces
that are joined and held together by a quick release pin. The
non-sectionalized arch assembly overall length is 113 inches and
the sectionalized arch assembly overall length is 98 inches
allowing easy transport by USAF aircraft.
(2) Header Assembly. The header assembly is made from
aluminum rectangular tubing with a cross section of 1 1/4 x 2 1/2
inches and has an overall length of 98 inches. Steel plates are
riveted to the ends to allow attachment to the arch assembly.
(3) Purlin Assembly. The purlin assembly is made from
tubular aluminum approximately 96 inches long x 1 1/2 inches in
diameter. Folding diagonal braces which have “U” shaped cross
sections are riveted to each end of the purlin. At the end of
each brace is a rotating brace stud and brace shackle. The brace
stud and the purlin end fitting lock into slots in the arch
assembly. Five purlins, one at the ridge, one at both eaves and
one at each base are required to join two arch assemblies.

cover assembly is diaper shaped, made of heavyweight, coated
cloth with interior straps to secure frame components and
exterior straps which bind the assembly together.
