This is the newest of the TOMCAT roof systems and similar to the 45' x 45' ladder roof. It is designed to meet customer demands for a more economic truck pack without sacrificing its loading capabilities.

Constructed with an optional perimeter of folding 20.5" x 30" - 52 x 76 cm truss, it uses a system of single truss ladders to form the internal grid.
The ladders are joined by TOMCAT's own unique intersection spigot connection. The use of the folding box truss along with the ladder grid allows for compact shipping and storage, but because of the unique design it still provides for a maximum uniformly distributed load of 20,000 pounds - 9,072 kg.

Available in smaller configurations, the 60' x 40' - 18,28 m x 12,19 m is shown here without the rafters for the canvas or the guy wires required for outdoor use.
