Nice to hear that your friend should recover well...This bridge issue is terrible. I bought a cougar a few years ago, and the failed bridge in your photo looks like the original bridge that was recalled. The replacement I got had a black sheath.
I used that cougar until I stepped up to a Treemotion a week ago, which I truly appreciate.
It's just a reminder that inspection is a vital part of EVERY climb, along with a record of use to keep track of cycles to failure. Always have a suitable replacement on hand, and if desired, just thread in a second bridge (a bit looser) as a back-up.
Be aware, and be safe everyone!
