6PCS M8 Hook & Hook Turnbuckle 304 Stainless Steel Turnbuckle Wire Rope Tension Heavy Duty Turnbuckles for Cable Railing Wire Rope Hardware Kit (M8, Hook & Hook)

I purchased multiple sets to use on a solar power array. The first few set worked perfect. The last set, although visibly the same, distorted slightly sideways under 60 pounds of compressive pressure. I switched the unit out with another, but it still did the same. The only thing that comes to mind is that the 304 stainless wasn't as strong.In future projects I will use these as well.

Works as expected and advertised. Well worth the price.

These are heavy duty. You can really crank them to get your cables tight.

Works good and plenty strong. The turnbuckles will hold unless there is lots of vibration. It will vibrate and loosen over time. Keep an eye on it or use thread locker if you don't need to remove it.

Good product

Very happy with these They are 6 inches long when in the fully retracted position, and they can extend out to about 9 inches or so. Good, robust tensioners. Don't know how rust resistant they are, but I'll find out. For now, definitely recommended.

These are awesome at getting the cables tight. It is almost impossible to get them tight enough to look good without them.

These hook onto the grommets and eye screws then tighten to stretch sunshade accordingly. Sturdy metal. Performs well. Size works in most applications. Handy to use and great value.
