4 PCS - Heavy Duty Jumper Starter Booster Cable Car Battery Charger Clamp, 25 years warranty

Replaced some melted and very worn out ends on my battery chargers. Seem to have great spring tension and are well built.

There is a lot of value, for the price I got- 2 sets for under $20.00. They seem sturdy enough, and for the average user, I am betting they will last as long as the cables. I have attached some photos, as I was not 100% certain as to how large a set of conductors you can fit in these. The answer is, plenty big. Aside from maybe industrial applications, the connector that that the cable goes into, will hold the largest conductor out there. Very first thing you want to do, is remove one of the rubber handle covers, and slide it down over the end of your cablr. After you strip the end of the conductor (aka, wire or cable) stick the bare end under the smaller tab and the insulated portion under the larger tab. Using pliers, large crimpers, visr, etc. Crimp the two tab pieces down, until snug. Place the newly crimped assembly inside the handle of the clamp, and use the provided screw and nut, to secure. Finally, slide the rubber handle cover, back up over the clamp. I have attached some photos, so folks can see what you are exactly getting, and how to rig your cables up.

I bought these to repair two battery jump packs that the cheap plastic clamps broke off of. Turning about $200 worth of equipment from junk to useful tools.They are heavy duty and I'm pretty sure the only thing that isn't metal on these are the grips that slide over the handles. I had read in another review to make sure you take the grip off that connects to the cable and slide it on the cable first and then connect. This makes it easy to install.They are of such good quality that I even took off the original clamp on the jump pack that wasn't broken and replaced it with one of these.If I ever need to repair jumper cables or jump packs again I will definitely reorder these.

As large as these clamps are I believe they would be hard for a person with limited grip strength or smaller hands. Great product and appears well made.

Good product

Very good quality, I purchased the to replace a broken one on my jump starter. Fits really well, I have my jump starter back now.

This restored my bad-clamped cables I bought as a teenager 35~ years or so back

The lugs bolt on to clamps making them serviceable. Be sure to get some hi quality flexible welding/battery cable and you’ll have a lifetime set of jumpers that the clamps won’t fall off.
