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

These jumper cables can handle anything from cars to trucks. They won't fight you when the weather turns cold unlike the pair these are replacing. The handle grips work with side and top posts. I am very satisfied with the overall quality.
