I have (8) brand new, never installed, Navtec Turnbuckle Eye Ends w/Toggle, part #D531-2424. Here's the description from HallSpars.com:
"The toggle (D531) screws on to the cylinder piston rod for small length adjustments (not to be tensioned under load). Cylinder Size: -22 Piston Size: 3/4in /19mm Pin Diameter: 3/4in /19mm Length Open: 7.63in/194mm Length Closed: 4.80in/122mm"
These turnbuckles are extremely high quality and heavy duty. They sell for $440 before tax and shipping on Hallspars.com. I'm selling these for half of that, $220 EACH, which is a steal for what you're getting. I have 8 of these turnbuckles available. These were going to be installed on a 53' sailboat, but the owner never got around to it.
