Dux attachment issues

[Brion Toss]

Hi there,
At the lower end, try Blue Wave's turnbuckles. Their jaws are wider and deeper than others, and the quality is very good. At the upper end, I am not clear just what configuration you are speaking of, but it should not be difficult to come up with a conventional tang that will accept those eyes. And you should definitely consider Collogo's "Cheeky tangs," that make the problem go away entirely. Just be sure you get the right length of throughbolt, with the threads cut so that there is no compression load on the mast. Consider shouldered bushings for the mast wall, regardless of the tangs you use.
Fair leads,
Brion Toss
