Polyester round slings are used primarily as a vertical pendant. The lifting capacity of polyester round slings vary with the size of the sling and the type of hitch used to attach the load. Each sling normally comes with two tags permanently sewn to the eye and eye sleeve identifying the size and capacity, as well as other important information necessary for the safe use of round slings. These slings are also color coded to designate the size of the sling.
