After more than a decade, this is a follow up video to my Lockwire video. A bit more detailed instructions on how to use the Safety Cable system to replace lockwire, saving much time in the process.
This tool is made by Bergen, and they have a website.
A lot of viewers are thinking this system has a weak spot at the crimpedon ferrule.
The ferrule is not the weak spot. The wire needs to be tight enough to avoid vibrating and wear, but it does not hold the torque of the bolt. The wire is there to keep the bolt from winding out and becoming a loose piece of debris that could cause a lot of damage.
The wire is not strong enough to apply the proper torque to the bolt. That's not what it's for.

Every time a safety cable is removed for disassembly, the cable breaks. Even if the ferrule itself is gripped by the pliers and force is applied, the cable breaks, but the ferrule never comes off. I've never seen it happen.

Following a suggestion made by many viewers, I went to the DMC site, and watched the vid on their version of this tool. Seems like a quality unit. I don't think I would use the wire tensioning handle, because of the 90 degree corner the cable is pulled through.
I'd have to try it though.
Interesting for a safety wire manufacturer, the comparison they make to using standard lock wire is a joke. They include three gigantic mistakes:
1 Using lineman's pliers instead of lockwire pliers.
2 The wire is incorrectly twisted from the starting bolt, in a way that would allow the wire to slip over the bolt head.
3 The pliers are placed where they will leave a mark, or nick in the wire as it enters the second bolt.
