280PCS AWG 4 2 1 2/0 Wire Ferrule Silver Plated Copper Crimp Connector with Heat Shrink Tube

I needed them for a larger car audio install in which I was using 0 and 4 gauge wire. The kit had sizes that fit snug on full size 0 and 4 gauge nicely. They crushed fine terminals that had allen key screws but I could not get a good crimp with a terminal that had a phillips head screw. I tried crushing them using a hammer crimper designed for attaching large gauge ring terminals onto large wire and even though they fit into the terminal they never seemed snug. I actually found a bolt with the same thread pattern and recrushed new ferrels into that terminal and then replaced the bolt with the original phillips screw and it seems to hold fine. They also seem solid enough that they wont shred apart or crack when compressing.

Great value as these appear to be silver plated copper and I'm fanatical about the base material when doing connections on my current-carrying installs.There were several complains on the ferrule sizing, but no issues with either 1/0 or 4 AWG. Also some call outs on the heat shrink tubing being tight. Easy fix: slip it over the small end of the ferrule and it can be pushed over the lip.

Great product fast shipping

Works great, could use slightly larger heat shrink

The shrink wrap could have had 1 larger size. Used this in a radio install on 0/1 ga and 4ga

The tips are fine, but all the heat shrink is the same size and too big for the 4 and 2 AWG sizes. Lame! If you’re using the smaller sizes, you’ll need to buy your own heat shrink tubing that fits. This kit should have at least two different sizes of heat shrink.

Los ferrules son del tamaño indicado, buena calidad, pero el termocontraible es de mala calidad.

Works beautifully. Is exactly what they list and does just as it should.

I should have looked closer at what I was ordering, it wasn't what I needed

everything is well packed and organized but it would've been great to have few 12 guage ferrules
