I know nothing about climbing. I use this to hook my K9s pinch collar and regular collar together incase one breaks I have a back up. For that it works amazing. Sturdy. Lays flat so there is minimal chance of it getting hooked on something else like longer cord type options. It's a little bulky with the twist to open part, but my dog is strong and serious so her safety and security is important.
