This is a computer balancer I bought when I had a small tire shop. I used it about 2 years but I wasn't very busy. It takes a three phase power supply but I currently use it on 230 with a static phase converter which I will throw in if it's necessary and the price is right. This machine has all the original attachments and a bunch of wheel weights with it. It's also go a dually wheel chuck. It's a little dusty from sitting out in the shop but it's in really good shape and working order. Send me a message with any questions if you're interested. I'll only accept cash for this.
