Our Stubai ratchet ring wrench is a really cool item. Because with it you can expansion bolt tighten super elegantly.
For this purpose, the keys have a so-called “ratchet ring” on one side. This means that they can be donned piece by piece using short movements of the wrist. This means you no longer have to “grip around”. This applies to both tightening and loosening.
Once in place, the nuts can be tightened in one go. This makes it much easier to set up the climbing route with expansion bolt .
The second side is always an open-end wrench of the same size.
