It was originally designed by Rock Thompson in 1989 based on the “Soloist”, another rope arresting device he designed as a self-belay for rock climbers. I personally conducted drop test back in the “90’s” when I worked for the University of Nevada Reno’s industrial fire school using the original design and we had no rope damage. I still teach rescue work and I still use rescucenders. We have been using them to acsend ropes and to tighten high lines for years. And there were other’s that also did test with the rescucender and they published their results with similar findings. There is a YouTube clip of one damaging a rope but if you look at the cam it is severely wore and damaged and should never have been used. This new design is really great as there is no more the little wire that people have gotten twisted or wrapped around the rope. I love this new design and the rescucender (both the original and new design) is the only hard ascender I use in rescue work. (Soft ascender being cordage loops tied onto a fixed line using an ascender knot, ie Prussic, Kliemheist, Bachman, etc.) However... High angle rope work is always dangerous, people working in this environment need to obtain professional training and always plan for the unexpected to occur and not totally rely on one piece of gear; always remove any slack in your rope systems to prevent or minimize your chances of having a shock load on your rope system. (My CYA Statement) YIS (Yours In Service) **Q: Can this work as an up and down control for roof work? Please advise if I need another type of controller?** A: I'm not sure what you mean by up and down control. This is a device that grips the roop and lets you ascend normally but you can't descend without manual intervention. (You have to hold the lever to let the rope out. As soon as you release the lever, it grips the rope.) If you are working on a roof with a rope affixed to the apex, then it would keep you from falling as long as you were disciplined enough to keep the rope snug in case the tension isn't enough to pull it out for you. **Q: Is this device mid-line attachable?** A: Yes, you can put the rescucender on the rope whenever and wherever you want. You just have to remove the carabiner in order to put it on or take it off. **Q: How smooth is the feed, any drag? Looking for something that can handle 11.4mm rope** A: I use the Rescucender to TR soloing. It feeds very smoothly and is super easy to use. I have only used it on ropes up to 10.0 mm. ## Frequently Bought Together - PETZL, Rescucender - PETZL - ROLLCLIP A, Pulley-Carabiner, Triact-Lock - PETZL, OK Carabiners --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/317122751-petzl-b50a-rescucender-openable-cam-loaded-rope-clamp](https://www.desertcart.us/products/317122751-petzl-b50a-rescucender-openable-cam-loaded-rope-clamp) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-14*
