These suspension rings have not been sent out for 3rd-party independent laboratory testing. They do not have an official certified weight/kN rating. Suspension is a high risk practice and should only be engaged in with someone who has experience, or under the direct supervision of an experienced individual. That said, our rings are made from 1/2" solid stainless steel bar.
