FJC45244) 20' 2-Gauge Booster Cable with 600 Amp Rating Parrot Clamp

Clamps are reasonably well crimped to the cable, which is copper-clad aluminum (not solid copper). The clamp grip is secured by a very strong spring. It would have been nicer if the contact area of the clamps had been larger than the edge of the teeths only.

I have made several sets of booster cables from welding leads and the parrot type clamps, and where much more expensive to make than these and were not nearly as long. These are good quality product, I like color coding, molded twin, and at a good price, they are just a little stiffer than weld lead wire but my kids vary excited to have in their vehicles, as these were Christmas presents.

Only used once. My vehicle wouldn't jump the stranded vehicle but a second vehicle did the job. I assume maybe my battery is on it's way out. But they seem nice & heavy.

These cables are well built and they fit in the old case that I used to have. I think that they will last a long time. They were delivered in a very timely matter.

I have had these CABLES for several years now - time fly's... - and i have loved them. i have actually Jump started 2 vehicles that other jumper cables didnt. The clamps on these seem to be very good, best i have seen.

I bought these cables because my son drives a heavy duty truck and needs heavier cables than we had. They have been very useful and seem to be of good quality.

Best Cables out there. they are long enough to stretch from front to back of car and works where other cables just can't carry the current and fail. Great idea for Christmas

Haven't needed to use them yet but I hope I don't have to for a while. They appear very well made and much better than my previous "cheapo" set I bought 12 years ago. I should have bought new ones years ago. These fit very well in the emergency roadside kit I am making.
