Tomcat has essentially taken conventional 12" X 18" light duty box truss and modified the components to provide a more efficient truss - at a more efficient price. The 20.5" x 20.5" version of (core) and accessories are being developed to complete the (core) product range and are expected to be available this summer. All Tomcat truss products meet ANSI E1.2-2006.
