RuiLing 2Pairs Full Insulation Car Battery Test Lead, 30A Protecting Alligator Clips Crocodile Clamps (Black+Red)

Yes. These are the ones.I needed something roughly this size. Insulated. I can always solder connections to these if I need to, but in most cases, for my use, I can use the simpler option and connect directly to a 4mm banana plug.The springs are very strong.The teeth are particularly grippy.I noticed only one odd thing. It didn't affect my use case, but might affect yours. Out of two packages, about half of the insulators fully covered the alligator nose. On the other half, the insulator was trimmed back to cover only about half of the nose. I personally would prefer the full length insulators, but I can live with the trimmed ones if I have to. I think the manufacturer should be more consistent about this and either make it an option or just pick one way of doing it, show just that one option in the photos and deliver just that one option.

Just as pictured. Replaced some larger clamps with these. Seem to be well made

I purchased these for use with my benchtop power supply, as up until now I've only been using little wimpy ones to deliver, at times, a concerning amount of current. These were to be soldered onto some 14GA twisted lead wire (ASIN: B095C5DFYX). However, I happily found out that the socket of these clips fits a standard 4mm banana plug, which I had purchased (ASIN: B0897LB83Z) for related purposes. So I could make some lead wires to easily hook up to my PSU.These have a very high clamping force for clips of this size and type. They aren't unworkable, but they'll keep a firm, possibly damaging grip on whatever you attach them to, so exercise prudence. If you are only connecting them to metal or other bare wire, I wouldn't worry about it.Anyway, would recommend for the purposes described above, I'm glad I bought them.

I like everything about these clips. They are solid, the jaws are sharp and shaped just right, and the insulation boot stays put and isn't slippery.

Replaced clips on a battery tester with these. They work GREAT!. Product gets 5 stars, Amazon Delivery gets ZERO. They cannot or will not (mist likely) follow the delivery instructions to for my house. Really dad because it's shorter to walk up the drive to the carport than to the front door.

Used for a quick 110VAC connection at a 110/220VAC Disconnect/Switch. I had an extension cord plug end about 1 foot long, strip the outer jacket approximately 6-8 inches, strip each of the wires <1.5 inches, twist and soldier the bare wire (10 or 12 AWG). Insert the wires into the alligator clips, crimp with your preferred crimping tool, then insert your soldering iron into the mouth to create the best bond. Take it to your disconnect, open, clamp onto your points (Gnd, Ntl, Hot) for 110VAC & now you have a quick connect for plugging items in. Examples: Vacuum Pump for HVAC, Power Tools for cutting, Etc.

Little smaller than I thought. But are strong and grip well

Can’t use for bigger wire sizes
