WCT0N-2 Wire Coupler Terminal Butt Connector With Set Screws 2 Pack (1/0 Gauge)

Just what I needed to connect my 1/0 awg cable!! Be sure to get cover with shrink tape when finished connecting so it seals it up and will leave your cable in perfect condition

Great connectors! Worked beautifully for my boat audio install. Would buy again!

First I purchased dorman butts but I would've had to use heating and crimping and for me. It was too much to do with such little space to work in. Then low and behold like magic, these surfaced and I was able to connect the new 1/0 Guage wire to my broken positive wire in minutes. It's made of super strong steel so it'll last forever and with the screw allen screws. I was able to keep the wires secure and keep current flowing for a strong reliable start every time.

I used them with 4 gauge wire and they seemed to work, but it felt like the threads were ready to strip. I covered them in a heavy shrink wrap. I would not use them without the shrink wrap.

I keep these on hand incase I have some high current draw wiring get too hot and burn through, hopefully I wont need them.

They work great. Trying to find the plastic kind of very hard. I will use these for now on.

Quality product

These are pretty decently made, but have a few design flaws. I bought 2 sets to use in coupling 6 gauge wire together going to feed a sub panel. I had read a prior review stating that you would need to back out the holding screws completely to get the wire inside the coupler. This was Correct. Removed the screws and the 6 gauge wire fit right in. But, the screws WILL NOT THREAD BACK into the coupler with the wire in place. Not 6 gauge stranded wire anyhow. And, the screws are fairly cheap, soft, and easily rounded out. I'll keep these to use down the road with smaller wire to save the hassle of returning. But, it stated they were for 6 gauge when I purchased them, and they were useless for coupling that size wire...FYI
