We have them on the base of the mast on the newer F18's. 17 mm bolt tensions or loosens the settings. If you want a turn buckle Ronstan makes a nice one that is adjustable. ![[Linked Image]](http://www.ronstan.com/images/product/RF1574-0606.jpg) http://www.ronstan.com/marine/product.asp?prodno=RF1575M0304I used the type above on my tiger and you can get it with a small arm so it is adjustable on the water. This looks like a great replacement for the nuke proof turnbuckle that NACRA orginal put on.... Would this be that same for adding an additional tunrnuckle? Just looking for something to compensate for the rigging it self as they are never the same... If you're just trying to equal up the sides spin the longer diamond wire to tighten the strands and shorten it( takes a little experimenting) or add one turnbuckle to one side. You only need it once though and it's one extra failure point. I also had one of the factory Nacra "nuke proof" turn buckles unthread the rod from the bronze barrel on the first leg of the 2001 Worrell. Cost us 2 hours right out of the gate. Lucky it didn't cost us the rig.
