Well, according to the Loos site, 1/4" 1x19 316 stainless (which is what I have) has a breaking strength of 6900lbs which is 3130kg, so that's not too far off from 2700kg. Not sure how much that 430kg difference makes in practice...

Wouldn't the crimped terminals have a lower breaking strength than the wire itself? I.e. the actual crimping?

If a man speaks at sea where there is no woman to hear, is he still wrong?
