This code only identifies the harness that makes part of the Power Big Tubing kit Cod. 1699. It can be purchased in addition to the 1699 or 1695 kits. This way, you can have an extra harness to use the elastic straps in pairs or as an alternative to the belt/strap in the 1695 kit. The sling is suitable for exercises with more elastics and, consequently, higher lifting loads. The sling is made of durable nylon and is padded and equipped with a half ring and buckle for quick closure.
