The third offering in the CORE product range is CORE 20. TOMCAT has essentially taken conventional 20.5” X 20.5” medium duty box truss and modified the components to provide a more efficient truss – at a more efficient price. At only 69 lbs per 10’ section, with the ability to sustain 3000 lbs total UDL over a 40’ span, CORE 20 offers a considerably stronger option.
