Roundslings, made of durable, high strength materials, are light-weight and flexible in construction. Roundslings, like web slings, are gentle to the load and provide some protection to fragile loads. A roundsling is seamless and tubular in construction with no stitched edges to become snagged or ruptured. In addition, roundslings are color coded according to capacities to allow easy identification while the soft pliable body of a round sling allows it to hug uneven and odd-shaped loads. Polyester roundslings stretch nearly 3% at the rated capacity and will return to the original length after the load is released. The cover of a roundsling protects load bearing yarns from ultra-violet degradation as well as abrasion. A roundsling is the cost effective choice in high capacity lifting or pulling applications.
