I am offering a set of SRT rope climbing handle ascenders (right and left) with body and foot straps, by Petzl. I imported these directly from a US arborist supply distributor about six years ago. I used them about a dozen times after purchase, and then stored them indoors. Since I will not be using them in the future, I would like to sell them to someone who wants them. Please understand that this product is used and consider using it at your own risk. The specifications are as follows: * Rope size: Φ10-13mm * Maximum load: 140kg (right), 100kg (left) * Model number: 17C0069528061 (right), 08065FR3778 (left)
