20.5” Generic MD

Generic Medium Duty is perhaps the truss that the production industry is built on. GMD has good structural properties and can achieve span lengths up to 50ft. With a 20.5” square cross section it provides a very economical truck pack and great versatility and can be used as a base for the Total Structures outdoor stage roof system. 

Built on the same profile, S4-PRT is a Pre-rigged version of this truss that is physically and structurally compatible, that will house a lamp bar of fixtures (ideal for Source 4 Par lamps) that can be stored in the truss for shipping and storage, and lowered through the truss at show time.
