Rings of all sizes and shapes are commonly used in rigging. Round rings are especially useful thanks to their shape, and these rings in particular are unique because they are made from Grade 80 alloy steel. This means they can be used on Grade 80 chain slings as a master link. Each ring is proof-tested at 2 times the Working Load Limit (WLL) and features a durable orange powder coat finish. Available in multiples sizes and strengths, up to 2-1/2" and 141,000 lbs WLL.
