A span set is also known as a polyester sling or poly sling, or is called a round sling. It can be wrapped around a truss or beam in a choker shape or draped over the beam in a U or basket shape, or can be used end to end. It is used in many rigging applications. We protect the span set from the edge of a beam or truss with padding to prevent any movement from potentially cutting into the span set itself. When rigging from a truss or beam, we use 2 span sets for safety. Some performance spaces require the use of black rigging to be inconspicuous. All our span sets are black.
