Freedom Rigging System: The name of this product tells you all you need to know. Admiral Staging has developed a modular rigging system that offers you as much constructional freedom as possible. This innovative system can be used suspended or standing and there are so many length and width variations of the suspension structure it would be difficult to calculate them all! Multiple tubes can be slide into each other in order to vary the height, while the width can be determined by various lengths of suspension tubes. With Admiral's Freedom Rigging System, you can rig just about any kind of luminaire imaginable including fixtures and yokespots. When you need to connect two length tubes to get your desired length, you have to use this easy connecting set.
