Strength & Flexibility in Lifting

Synthetic Polyester

Round Slings

Stren-Flex® Polyester Roundslings


  • Color-coded for positive sling capacity identification
  • Double-wall, woven seamless cover for longer sling life
  • Durable capacity tag provides serial number traceability
  • Red-striped white core warning yarns provide positive indication for sling replacement
  • Low elongation (approximately 3% at rated capacity)
  • Consistently matched lengths
  • Soft and light weight for easy rigging
  • No loss of strength from abrasion on cover
  • Easily conforms to the shape of the load
  • Sling life can be extended by rotating bearing points

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.
