Well Made Power Distribution block for Adding Automotive Accessories
Well made product. Sturdy and easily to install. I used this in a restoration of a 1948 Dodge pick-up restoration to provide easy distribution of power in conversion to 12 V negative ground from 6 volt positive ground.

It’s a great heavy duty buss bar.
This was a great buss bar for my dune buggy build. Lots of terminals for accessories. Good heavy weight to it.

Worked great for my application
I needed this for my RV and it worked out great! I had several negative terminals that were sharing a single screw attached to the frame. I needed to add negative wire for a solar charge controller and this bus bar worked great. I did discover after the initial installation that I needed to ground the bus bar to the frame. But everything works and looks good now.

Overall well made and shipped quickly
Small and was what I was looking for. The only negative feedback I have is the plastic nuts that hold the cover down. Overall well made and shipped quickly.
