SRT Rope Climbing Handle Ascender with Strap (Right/Left Hand) by Petzl

This is a set of Petzl ascenders (right and left hand) for SRT rope climbing, with body and foot straps, directly imported about 6 years ago from a US arborist supply distributor. After about ten uses, they were stored indoors. As I will no longer be using them, I would like to offer them to someone who is interested.
Please understand that this is a used item and consider using it at your own risk.
Special specifications are as follows:
- Applicable rope size: Φ10-13mm
- Maximum load: 140kg (right hand), 100kg (left hand)
- Model number: 17C0069528061 (right hand), 08065FR3778 (left hand)
