300Pcs 12 10 8 6 4 2 1/0 2/0 Wire Ferrule Tinned Copper Crimp Connector Electrical Cable Pin Cord End Terminal 8 Sizes Assortment Kit

These are awesome. They’re just as described. High-quality and we’re great. I use them to install my car audio system.

These are good for clean car audio amplifier installations.

Good ferrule set, if you do audio stuff you need these.

Ok

These are a must-have for clean and professional installs! They are attached easily with heat shrink to the ends of your wires and make maintenance a whole lot easier. No fraying, no crunching, and no hassle. They crimp easily and provide a super clean look for all wire terminations.

I honestLet didn’t have high expectations for these ferrules given the low price and obvious off-shore sourcing. But now that I’ve received them I gotta say I am very impressed! The look and feel great. I’m the photo you can see that I have installed them onto the ends of an 8” piece of high-end, 1/0 pure copper cable. They fit like a glove! This cable had previously been attached to a distribution block with set screws, so the ends were pretty gnarly. I was able to twist them down and get them into the 1/0 ferrules very cleanly. I would say that they are perfectly sized. I also love the range of sizes and quantities included in this kit. One thing to point out... I looked over a variety of ferrule kits. Nearly all of them are sourced from China, and nearly all of them list “#1” gauge wire. These RockDig ferrules were the same... except that they note in their description that they are mis-labeled, and should be designated as “1/0”. I feel this demonstrates an attention to detail that puts them above their competition. Very pleased with this purchase so far!!

Excellent kit to cover a wide variety of applications. I don't know why some people left complaints about this product. I've been doing custom car audio installs for years and theae ferrules leave nothing to be desired. If you kink or crush them before putting over your cable/wire, yeah, it's a pain in the butt to slide them on. But that's not the product's fault. That happens work even over-priced ferrules. Zero amperage or voltage drop from distribution block to cable using these. Cooper ferrules with TiN coating. Not much more to say. They work great.

Easy to crack them during crimping. The wall thickness should be increased at least 50% to reach a better-quality ferrule.

Todo bien

Works well with various wire sizes.

The material is a bit thin, leading to distortion when clamping in a connector. Quality is ok for the price.

great product ..........nothing else will do when you need them

Completely useless you can’t get these to stay on the wire, material is thin and very questionable, you cannot call these ferrules, conductible wire shield at best but honestly save your money and get some decent lugs not even sure if these are going on any of my projects
