Mazzella Single-Path Roundslings are made from a continuous loop of 100% polyester load bearing yarns. The yarns are covered by two polyester tubular jackets. The outer jacket is color-coded for quick visual capacity recognition. If the inner load bearing fibers are visible, remove the sling from service immediately and discard properly. Use the easy-to-read chart below for single-path capacities. For greater lifting capacities, see our Twin-Path® slings.
