Yeah, don't use these for climbing.
Climbing carabiners (aside from gear 'biners) are ALWAYS locking.
Climbing carabiners are rated in Newtons not Pounds. Force isn't the same as load.

riboYou're correct, climbing carabiners are rated in Newtons, and I wouldn't recommend climbing on this, but force is actually equivalent to load. http://en.wikipedia.org/wiki/Structural_load
Pounds are a measure of mass, not load.
I think you're meaning to say force isn't equivalent to mass, which it isn't but one can easily be established from the other using Newton's second law. The only discrepancies come with drastic changes in elevation which can result in differing values of gravitational acceleration.

GonltruckRight, given that they have a time-series chart of the applied load over time, you can derive Newtons from that chart. You're right, a "load curve" is equivalent to force, but I think I meant that a load failure test isn't the same as a force rating test. A device that would fail at their given load curve might fail far earlier if a lower stress is applied much more quickly, quickly being faster than you could extrapolate from calculating the derived force from the test.

GonltruckTechnically pounds are an ambiguous unit since they can represent either force or mass. Traditionally pound is a unit of force in my experience. Note that the definition of a pound of mass is given in terms of the kilogram (a real mass unit).

GonltruckPounds are force, or weight. Kilos (or slugs for americans) are mass.
