Exactly as described

Needed a 12mm tensioner for a garden fence project. This fit perfectly and holds the wire rope very securely. Highly recommend for DIY projects.

Good strength, fast shipping

Arrived quickly and well-packaged. The metal feels heavy and durable. I deducted one star only because the eyelets are slightly smaller than expected, but they still work with my cables.

Professional quality

As a professional rigger, I am picky about my hardware. These turnbuckles meet industry standards and perform reliably under load. Will buy again.

Great corrosion resistance

I use these for outdoor canopy supports. They have been exposed to rain and sun for weeks and still look brand new. The 304 steel is legit.

Perfect for my sailboat rigging

The stainless steel quality is excellent. No signs of rust after a month in saltwater conditions. The threads move smoothly for easy tension adjustment.

Solid build, slightly stiff at first

Very sturdy turnbuckle. It was a bit tight when I first received it, but after working the threads back and forth, it operates perfectly. Great value for the price.

5 FAQ

Q: How do I prevent the turnbuckle from loosening over time?

A: Once the desired tension is reached, you can secure the nuts by tightening them against the body or using locking wire/cable ties through the eyes to prevent rotation.

Q: Does this come with the wire rope included?

A: No, this listing is for the turnbuckle tensioner only. Wire ropes and other rigging accessories are sold separately.

Q: Can I use this with a 10mm cable?

A: This turnbuckle is designed for M12 threading. While you might be able to adapt it, we strongly recommend using it with compatible 12mm fittings for optimal safety and performance.

Q: What is the maximum weight this can hold safely?

A: The working load limit is approximately 2.5 kN (around 250 kg or 550 lbs). Please do not exceed this limit for safety reasons.

Q: Is this turnbuckle suitable for marine environments?

A: Yes, this is made from 304 stainless steel which offers high corrosion resistance, making it ideal for marine and outdoor applications.
