350A Bus Bar 12V Marine 6 x 3/8" (M10) Terminal Studs 12V-48V Power Distribution Block with Cover,with 4PCS Battery Lugs and 4PCS Heat Shrink Tubing Busbar for Boat Automotive Car

I gave it a 5 because of the fair price compared to other brands the plastic is cheep the bolts are loosely attached in but the bar it’s self is nice and thick and heavy

It worked perfectly for my solar system; they’ve definitely been mounted for over three months, and there isn't a trace of rust.

I have both choices A and B the open and the other one. I like them both. Mounting is easy and comes with everything you need. The wire copper lugs are great quality and the heat shrink is the perfect size. The build measurement is alittle off. I'm sure if there's was more platting then it would be 3.2mm like advertised. But it handles 100ah easy. Haven't tried anything higher. Haven't needed it too. The bottom caps over the bolts fell off the open caps I mounted earlier on all 4. But theses seem to stay in place I guess the other ones weren't glued properly. It's a good buy for the price plus the extras are great quality which you're not going to get with the others. Real buyer not a vine person.

Work as they should

Solid bus with 1/4" thick plated copper bar and heavy lugs. Much better then the screw-down bus I had prior. I knew it was going to be solid when I first grabbed the package - heavier then expected.

Easy to install, works great, and it seems like high quality

When your build just keeps running it's tab up and up on you like a Cardi B song, finding stuff like this with a decent price is what you need unless you have a steel fabrication shop where you can tool a solid chunk of steel/copper in to a high amperage bus bar this is it right here. Days of me just throwing a 100 watt amp on any old wire unfused days are over, with todays high current pro car audio you have to follow guidelines if you want you equipment to sound good, last and not light your ride on fire. I almost used a pair of 150 amp bus bars on a 400 amp lithium battery bank recipe for disaster right there.

Worked great for what we needed to do great bus bar.

I was really just looking for a ground bus bar but I'll take both. It started with just grounding everything at the front of the bus of my schooly . Then I realized I could use a second set. I'll use it on my solar panels.
