Olive, Real or rated carabiner's have their load ratings stamped or cast into the main body with load ratings listed for three different directions. The only place that I would purchase them is at sporting goods store's (like REI) that cater to rock climbers. We use a combination of quick releases and carabiners as the pole straps on the marathon vehicle.
