My new turnbuckles (no issues with them coming loose)

[kmcintyre]

There's been a lot of turnbuckle "issues" with them coming lose, etc. and I've seen people use 2 nuts, etc. Here's my solution.

I bought them at a rigging supply store and they weren't that expensive (maybe < $10 each). They are high strength and I doubt they are coming loose! There's a nut and a cotter pin to keep the bolt from coming off.

That's essentially what I use too. It's never come loose, although it is more work to put them on. I still check on them from time to time, but I doubt they ever come off.

That's what l use. I double nut it and it does not move. If they did ,it would still be hanging on the eye bolts.
