Why do you guys use carabiners instead of quick links, which can be wrench tightened.

Quicklinks are usually too narrow to allow clean loading of 1" webbing unless you get the very large ones. This especially becomes problematic if you are making a primitive tensioning system trying to use it as a makeshift pulley. In addition you still have the issue of having to manually thread everything instead of clipping or carrying a wrench every time you setup. If you were to make that trade off 50kn rap rings would be a better option.

That said, steel carabiners are an excellent compromise as they offer higher strength as well as the convenience of clipping and they are even lower friction than aluminum (according to the SAR reports I've read). Most people however aren't willing to dedicate such spendy equipment.

Tri-loading and not checking gates are the most common reason for slackline biner failure - and those are really caused by inattention or insufficent knowledge on the rigger's part making more of a human error issue.

I agree with Jim, this looks like an open gate failure. Most likely it was an old biner with a stickey gate, it wasn't fully closed when loaded and thus it failed, probably even at it's rated open strength.
