    A very reliable auto-locking Carabiner

    Posted by K Drake on 8th Jul 2016

    I have used a number of auto-locking carabiners over the years. This one has been my favorite. Easy to operate and reliable, even in grit and mud, and the locking feature has not been compromised with age - unlike other name brand products I've used.

    We also have used this Carabiner on a zip-line at a summer youth camp. They literally get opened/closed hundreds of times each week, during the Summer and Fall. Liked them so well, we've purchased more.
