And the Norseman terminals that gave way at 70% of rated strength were giving way at 70/150 of ultimate or 47% of ultimate strength. Brian W Just go up a size on everything and forget about it, Brian! LOL Ha! You are talking to Mr Cheap, remember.... I don't think twice about using aluminum ferrules on rigging and squeezing with a pair of bolt cutters with the jaws ground to shape.(Copper would be better.) In that scenario, my idea of adding a safety margin is using TWO ferrules to hold a hard-eye. Ferrules cost a quarter or so, not a hundred or so. Hard eyes under a buck. All the same, I have a hankering for those bolt up terminals, and I like the idea of the Suncors, even if I can't beef up their reserve strength, AND they cost way, WAY more.... Brian W If you are being cheap why not learn to splice cable. A properly spliced cable will be about 90% the cable strength and cheap. All you need to splice it is an ice pick.
