Polyester round slings are a great alternative to nylon slings as they have a substantially less stretch value. The pliable body will hug the load much better than a nylon lifting sling also which will prevent your slings from locking up on the load in choker hitches. We currently have the polyester round sling available in an endless round slings. Polyester slings are ideal for applications requiring more strength, less stretch and chemical conditions where a nylon lifting sling would not be appropriate. Round slings are wrapped in a flexible polyester fabric to protect the load bearing yarns from abrasion and damaging UV rays. The flexible polyester jacket is color-coded to help recognize the endless slings or eye & eye slings weight ratings and have identification tags indicating size, type, and capacity.
