For sale is an assortment of 29 various carabiners, all used. I don't believe they saw heavy duty or serious falls as my friend and I were easy climbers, but I can't vouch for their safety. Either way, there are a lot of them for a cheap price. All 29 can round out your rack at $20 plus shipping (flat rate is 10.50, which is the cheapest way to go because all in the weigh almost 4 pounds!) Contact Steve at sjwark@gmail.com
