Buy a nut of each possible size, in a left and right hand thread.Hi, I have an 82' c30 and would like to replace the closed body turnbuckles with open body ones. Does anyone know what thread size these are?
Having nuts around to test with is handy. But it's going to cost as much as an inexpensive pair of calipers while giving you a tool that only does one thing, compared to the nearly limitless uses of the calipers. (To say nothing of the inconvenience of finding left-handed nuts.) Also, you can't use that method to determine the thread of something while it's assembled. And, if you really want the system to be usable, you'd need metric nuts, too, more than doubling the cost.Buy a nut of each possible size, in a left and right hand thread.
This ^^^.Read the catalogs, dude.
It would be quite unusual to have 3/8 on a 30 footer. You need to measure the SS wire, not the white plastic. Buy the new stuff as bare wire, not plastic coating. I sure wish they made blue.I found some calipers and the lowers appear to be 5/16 and the uppers 3/8. I hope
I measured the threads. The wire is 1/4 for the uppers and 3/16 for the lowers. I'm not sure what plastic you're referring to but I don't have any plastic around there.It would be quite unusual to have 3/8 on a 30 footer. You need to measure the SS wire, not the white plastic.

The wire can come with a plastic coating of some type, or you can buy the wire without it, so it should be cheaper.I measured the threads. The wire is 1/4 for the uppers and 3/16 for the lowers. I'm not sure what plastic you're referring to but I don't have any plastic around there.
You are right ! EVEN WHEN I SAID LIFELINE HE STILL DID NOT SPECIFY HIS SITUATION. WE STILL DON'T KNOW for sure, DO WE?I confess I'm amused that a topic like this could result in 11 replies. First, if you can't figure out what size turnbuckles you have, maybe you shouldn't be attempting this on your own. Second, it seems there's confusion over whether these are for standing rigging or for lifelines, per the plastic-coated comment. So, what is it? This is something you can easily look up.
