    I developed patented technology to prevent runaway trailer accidents. This technology is a bar system versus the age old chain system. My product is made and tested in the USA and is far superior to the subpar products made in China. I won the Innovator of The Year Safety Award in my home state of Louisiana, stating this could revolutionize trailer towing safety! I also have engineering data to prove it is the best and latest technology to prevent these runaway trailers accidents. A trailer should never separate from its towing vehicle. I have 50 plus years in the metal trades field. There’s much more to my technology than I can cover in this brief paragraph. I totally agree the u-haul video is totally misleading and need to be revised and or removed. The stats on runaway trailer accidents show 4 to 500 deaths per year and 15 to 20,000 injures caused by these tragic accidents!!! Something has to be done to make our highways safer so as to prevent our love ones from these runaway missals. Thanks.

    Great article! Getting the right length of safety chain is very difficult because there is so much variation in receiver height and hitches between different vehicles. Linklock.net makes a length adjustable safety chain attachment for trailers, I’d love to get your thoughts on it.

      Thank you for sending this link. I read their website and really like the concept. I also reached out to them for more information and for something to share on our site about their product. First look says this is a really great approach, so thank you again for sharing!

    Good data on chain strain but no direct real world data is provided showing what happens to various chain strengths with a varying degree of twist when subjected to actual strains equivalent to a de-hitching scenario between a tow vehicle and trailer. So, in the end there is too much extrapolation that I cannot use this article as a definitive resource. Yes, the best thing is to use the proper sized chain. But, the article does not definitively tell me anything more than the author’s opinion wrapped in a high degree of indirect metallurgical data.

      Thank you for visiting, reading, and thank you for the comments. You are correct, this blog is sharing experience with engineering knowledge and judgement – opinion in your words. I would love to do the testing and provide the analysis you seek. Please let me know if you will fund the project?
