## Customer Reviews

### ⭐⭐⭐⭐⭐ Heavy duty
*by R***. on June 2, 2025*

Bar was larger than I expected. Exceeded my needs. It is great.

### ⭐⭐⭐⭐⭐ Well made
*by R***S on May 24, 2025*

Well built power distribution bar! Gives me a power point under the hood now that my battery is in the trunk.

### ⭐⭐⭐⭐ Good. Big.
*by B***L on December 10, 2024*

I wanted to get all the pos leads off my battery. I knew this was big but if you actually want to cover up the power rings/connectors the size is needed. Comes with everything you need. I do not like how the top connects. The nuts fit underneath but they will fall right out. I had to wedge them under and then screw the base on, which is trick. I only used two. I also had to break the side center out for the wires to come out the side. After all was done it does the job and looks pro!
