Also called endless flat nylon slings or type 5 lifting slings, these continuous loop slings are formed by joining the ends of the webbing together with a load bearing splice. To measure: Nylon round sling measurements are determined by laying the sling flat and measuring from one end of the webbing sling to the other. The endless nylon sling capacity will vary with the number of plys (from 1 through 4), and with the type of hitch used in the lift.SpecificationsVertical Capacity: 30,600 lbs.
