### ⭐⭐⭐⭐⭐ 







  
  
    Nice quality bus bar with a cover
  

*by B***F on Reviewed in the United States on January 6, 2017*

If you're one of those people who have like 10 wires stuffed under one screw for the accessories running in your car then think about running 1 heavy duty cable to one of these bus bars then you'll have a nice neat place to get your 12 volt battery power from. This is designed for the positive side or hot side and is isolated from it's mounting. What I like about this product is that it has a cover so that you are less likely to touch a terminal and short out or ground unintentionally. This will be good to run some high-draw accessories but not like an automotive starter motor or something directly. Just know this is positive (or negative) only and you will need another for negative side.

    Great way to clean up your wiring
  

*by A***R on Reviewed in the United States on April 4, 2019*

Used on my race car as a power distribution block in the engine bay. The battery is in the trunk of my car. I used this to power cooling fans, the starter motor, and other accessories in the engine bay. It is nice because it has large 10mm studs for large wires, but also has some smaller phillips screws for smaller power wires and terminals. Has a nice cover with plastic acorn nuts as well. Overall a nice piece and exactly what I needed for my project. I would absolutely buy again.

    Holding Up Well
  

*by D***B on Reviewed in the United States on July 16, 2018*

I was looking at installing some accessory lights on my vehicle and I realized I needed some type of intervention. I already had four or five accessories attached to the positive terminal of my battery and it was a mess. This distribution block provides a nice neat point of attachment for all that power and really cleaned up my situation. So far it's held up very well and everything seems to hold in place securely. Didn't experience any problem with the studs stripping out of their plastic base fixture. My only concern is how well the nylon cover nuts will hold in place when subjected to constant vibration such as a washboard road. Pleased with the purchase so far.
