You can't make them for this price

Why did I pick these, I was an Electrician in the Coast Guard And if you know anything about the Guard, you don't get A second chance when you are saving people's lives, so I believe They want to give you the best opportunity to save someone's life, The little cheap jumpers that are $ 9.99 I think they are dangerous to begin with they create A great deal of resistance and that creates Heat , These Jumpers are strong enough to Jumpstart A D-8 Catapiller Bulldozer , They are 20' long and you can even Jump someone stuck in the Mud that has run their Battery down using their Winch. I went into A discount company to see if I could purchase the Wire and the clamps to make these, Short story ; You Can't, Thank you for making these for me, Jim

I like the 16-foot length since batteries, according to Murphy's Law, are always on never side-by-side. Not sure about how well the grips will continue working with use and age. One of my batteries have small heads and took a bit of time to get a good hold. Otherwise, I'm happy with my purchase.
