I have 2 or 3 lockers on my rack. This is always one of them. It's a great biner that doesn't take up too much room and has a pretty large gate opening that works easily for any anchor/power point. It spins pretty well with 7 spins up and about 5 spins down with gravity. I'd be willing to use this as a belay biner; I'm sure it could do a munter, and it handles clove hitches like a charm. Basically, it holds whatever I need to fit into it, and is happy about it.
