The installation of permanent anchors for rock climbing is an activity that only experts with substantial knowledge and experience in regards to many factors should engage in. Failure to place anchors properly could not only jeopardize your life but could also jeopardize the lives of other climbers that will rely on the anchors you have set. Furthermore, ignoring local customs and restrictions on setting anchors could jeopardize climbing access in your area. Make sure you fully understand all of the issues involved with setting anchors for a route before you do it. Also, it should be noted that although Campsaver sells Rawl/Powers bolts Powers specifically states that their bolts are not designed for rock climbing and they make no guarantees about the safety of using their bolts as rock climbing anchors. Buy and use these anchors only at YOUR OWN RISK!
