Using my digital fish scale, I just put 50 pounds of force on a SS #2 S biner. At about 15 you can see it start to flex, but between 20 and 50 there isnt much more noticeable movement.
And the flex did not extend beyond the notches the gates fall into. It was very minimal.
Sandy...Theres time. Ill see about getting a large order in next week. I shot an email off to them to see if they can do better on the prices if I order over 20 of each.
