4 Post Power Distribution Block Bus Bar Pair with Cover - Made in The USA - 250 Amp Rating – Marine Bus Bar, Automotive, and Solar Wiring – Battery Terminal Distribution Block - (Set of 2) (3/8”)

Used these to mount a sprayer on back of gator as power supply very good quality now all I have to do is connect clamps to blocks and off I go less than one minute no old power port to mess with I also installed a breaker on this circuit to prevent any mishaps

I thought I was losing my mind when I started to wire everything and my rings werent fitting on the terminals. I was sent a 3/8 neg bus bar and a 5/16 positive bus bar. Fortunately I have rings for both, but its definitely a pain to have to go back and forth. I would return to switch out, but I can survive.

These are built pretty good / sturdy. It does have a plastic base but is made of pretty durable plastic. Only reason it lost a star was because the studs were so big. Was going to use them for car audio but will use them now for something else. Overall a good product though.

Bigger than they look.

Just perfect

I had high hopes for these as I need a 4 post bus... I put on one wire and tightened it down. I decided to make a change so tried to remove the nut. Nut will not come off and since the bottom is plastic the head of the bolt just spins. These are junk. Buy them at your own risk.

I do ALOT of wiring, this perticular project is for myself, i had to modify the buss bars for my perticular application and the material they were made with was able to withstand all the adjusments i made, and still is a quality piece of the entire design.

This was my second purchase. I liked the bus bars I bought the first time, so I bought them again. I used them in the construction of a full-capability portable amateur radio station, and opted for these over Anderson Power Pole buses. The bus bars are less expensive, and can handle 10 times the current of the Anderson products. As a result, they are safer. If for some reason, a dead short occurs, then with the 250 Amp capability, its not likely these would be damaged.

These ended up being perfect for what I needed. They fit and so far have stood up well, especially with the constant removal of wiring setting up for the project that they are in. Would recommend these to other people.

Nice heavy duty buss bars.
