Upgraded Bus Bar 250A 12V Power Distribution Block with 5/16" (M8) 4-Posts Terminals Block with Cover for Automotive, Marine, Battery System (Black)

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

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

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!

Can't beat it for the price

Easy to install. heavy duty product.

Installed these on my travel trailer's DC power supply. Through the installation I was pleased with the quality of the product and actually purchased a second pair.

I purchased the 5/16 block set to install the 12V battery bank for the solar conversion in my RV. I ordered cabling with 8mm connectors, from Amazon, and everything went together without a problem. Connectivity is very easy. The blocks make power distribution extremely easy. This was a retrofit for an RV with only shore power. Now, with the inverter, we have enough power to run everything. Highly recommended if you need power distribution. Would buy again.

Woks well as a buss bar but the cover is atrociously badly designed. there is no chance it will stay on in a vibrating environment, i tossed it and dressed all the wire to work without the cover.
