Bare Terminal Posts

I haven't bought these because when they are fitted , there is no cover / insulator for these fittings, this makes it very easy to short from the terminal to the vehicle negative .. the bodywork..All it would take is a slip with a tool . this would short.. and due to the power of the battery, could weld the tool to the body / power post.. or melt the power cable.Other suppliers include insulating boots to stop this.Stay safe...

Quality product with rapid delivery

These are seriously solid and should handle high currents no trouble. I was pleasantly surprised at how quickly they were delivered given they came from the States - less than a week.

Exactly what I needed!

Easy installation and made wiring clean!

They let you access your battery from an enclosed box.

They are beefier than they look in person. They use the same size holes as any other Cigarette lighter or USB PowerPoint that I've purchased in the past. You will need 4 cables to use them. Two cables that connect to the battery inside the box. And another 2 sets of cables to connect the outside receptacle to your devices. They are extremely well made. They don't feel cheap at all. You can mount them on metal or plastic. It doesn't really matter.
