I replaced the anchors on the first pitch of Neptune last week with new Metolius rap hangers and 4" Rawl power bolts. The condition of the old hangers was dangerous. The penny acting as a gauge shows the wear, a good 1/8 inch of material missing. What you can not see is a sharp burr on the outside edge of each hanger! Just a note of caution to our new climbers - DO NOT top rope directly through hangers, use your own draws . Granted the hangers are 22 years old but we have all seen party's in the area using the anchors without draws for top rope sessions. Note I will return and finish patching the old bolt holes. Was having some issues with the expoxy due to high temps.
