The Modular Rigging System is designed for improved speed and safety when rigging stage sets. Doughty intends the system to be an alternative to homemade drop arms. The system uses connectors to give a SWL of 220lbs (100kg) and enables the rigging of luminaires from truss or fixed tube barrels. It also provides for a range of configurations. Manufactured from high tensile aluminum, the drop arms come in lengths of 9.84" (250mm), 19.68" (500mm), 39.37" (1,000mm), and 78.75" (2,000mm), which can be connected using conical couplers to create larger drops. H-Frames are 16.3" (415mm) and 39.37" (1,000mm) high, with connectors available in sizes of 9.84"(250mm), 19.68" (500mm), 39.37" (1,000mm), and 78.75" (2,000mm). All have a safe working load of 220lbs (100 kg) and are available in powder-coated silver or black finishes.
