Good quality safety lock wire - I'm using it on my sailboat shackles
Nice stiff safety lock wire. I live on a sailboat and have many shackles and other hardware that require safety lock wire. I have found this product to be strong, very stiff (a good thing), and easy to use. The dispenser is well thought out and has a couple of spots to fold the wire to keep it from dropping back into the dispenser. I love that I can pick it up, grab a wire tool, snip off a section, fold the end and get to securing my hardware. Works perfectly. I don't anticipate any issues with the quality of the stainless steel. Since I'm in an ocean environment I will know quickly. I'll update this review if there are any issues. I am confident enough with this product that I put it on my most critical shackle - the anchor shackle.

The durability is high, this size works perfect for my needs, the use possibilities are endless, being stainless steel is rust resistant, bendability is great, I use it quite often, a great value for the money , easy to use ….

Very Good Stainless Steel wire.
I've bought this product before. SS safety wire has heaps of other applications. Great addition to making fishing gear. Pay attention to the size you order though to make sure it has the flexibility and strength you need.

So good!
Got this to use with my clamptite tool because a guy on here said it works and it’s so good! Very strong wire. Other stuff was snapping on me and I can crank this as right as possible and it won’t let go! Definitely worth buying! I will be getting more for in my other trucks!
