InstallGear 4 Gauge AWG Tinned Pure Copper Lugs Ring Terminals Connectors with Heat Shrink - 10-Pack

I really liked the heat shrink tubing that came with this one, the metal was a little tough to crimp compared to full copper. But they work and they are strong!

Best terminal connectors iv ever used. These are super heavy duty there really really good. Way better than others iv order at the same price. Make sure you have heavy duty crimpers you aren't gonna be doing these with anything less than the large bolt cutter style crimper's.

Convient bien pour travaux électriques.

Got these to do runs from my bus bars to my amplifiers in my marine audio setup. No issues so far. These are like 80% cheaper than the Ancor tinned connectors too. My stereo plays loud and clear and my wiring looks very clean with these.

Worked great. Used it for car my amp ground wire.
