Fastronix Premium High Current 3/8" Thru Panel Battery Terminal Connectors USA Made

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...

Well made with good hardware included. Have purchased at least 5 of these. Use them for solar energy storage, custom battery boxes.

Came quick and as shown!

So far definitely work as described. Only down side is the size of the hole you have to drill but it is what it is.

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.

Good construction, materials. I needed to get through a camper's firewall and these were two of the plastic threads too short. Had to spend an hour each one to modify the opening and the bolt. Probably deserves five stars, but all that work due to length had to be acknowledged.
