When you've lowered off your project more than any other climber, you might as well take responsibility for the worn-out anchors up top. We screw Camp USA's Oval Quick Link to the bolt whether we're equipping rappels or fixing quickdraws. The 8mm requires a 14mm open-end wrench, and the 10mm requires a 17mm open-end wrench. The 5mm Quick Link is not CE certified.
