The FIXE 316 Stainless Steel Double Ring Anchor (#DRA316-3/8) is our strongest Top Anchor. Each unit is rated to 25kn. These units make excellent Top Anchors on multi-pitch routes. The high strength and double ring design offers multiple attachment points helping organize belays. The Double Ring Anchors should be placed on the same horizontal plane, at least 8" apart in good rock. This unit should be used in pairs or with another FIXE Top Anchor unit.Fixe has been working on improving its anchor range with a highly corrosion resistant material (HCR) in order to increase safety in environments of all kinds, including marine and corrosive atmospheres, during a longer period of time. Our 316material has been specifically developed to help withstand Stress Corrosion Cracking (SCC) and minimize Galvanic Corrosion (GC). The material also has improved characteristics compared to common corrosion, mechanical resistance and superficial wear and is far superior to conventional stainless steel products.
