High quality and great look.
Excellent quality, function, and look! I used them for an over-engineered and high power solar system on my RV, and they didn't disappoint. I don't remember if the ad even shows this, but you can choose which sides to use or keep closed. Definitely recommend, and I'm pretty picky.

Very well constructed
Very thick plastic and a very nice platted bar. This will hold up nicely in the back of my boat.

Worked for my needs.
Nice bus bars. I added an additional layer of dielectric insulation to the bottom due to the thin layer of foam backing being the only insulator for the bus mounting screws and the surface you install it to.

Bus bar
Big and heavy duty, easy to connect and work with. Will say was MUCH larger than I anticipated but still excellent.
