Quad top rope anchor Be careful when walking around the top of a crag un-roped. As for a TR anchor, I'd worry with the use of non locking carabiners. Edit: For either the quad or masterpoint anchor as a top rope setup, only the carabiner that the rope is going through needs to be a locker (1 or 2 depending on paranoia). Select the strongest anchor piece and clove hitch the rope to it. If you're setting up a sport climb for top roping where the bolts and anchors are on the vertical face and you can visually inspect the anchor at any time, then it's fine to use non-locking carabiners. Agreed. It would also be best to understand how anchors work in different scenes. Moved Permanently. We all get to choose an acceptable level of risk. Works well for me for 3 piece anchors, don't believe I've needed to extend a leg with a sling yet (relatively new to trad). ihodtpjuyysbjguvpwdiopdegwvppubwssvbzrayqsezlzjilninqcygtaxixghyslymxdabfshsjzegadypo
