2pcs 300A Bus Bar Box Nickel Plated Brass Power Distribution Block with 4xM8 (5/16 inch) Positive Negative Ground Battery Junction Block Buss Bar with Cover DC12 24 48V（Red & Black）

Great quality. Rigid. Used as a junction box for my RV.

Although I wish the spacing was a little larger for lugs as I use 4/0 gauge and I need the room. So, I have to ago angle them to make them fit.

I wasn't going to write a review until just now. Good design should be rewarded, though, and these are well done.Using this bus bar in a 2S2P battery bank for a solar installation, I only needed three posts and, more importantly, I needed a bit more room to swing a connector to help route a cable. I thought to myself, "if that fourth post weren't there, things would be easier..." I had nearly resigned myself to cutting away the unneeded post when I thought, "I wonder if that is just threaded in..." With a little effort I was able to locate the screws holding the bus bar onto the plastic mounting and remove them. Of course I was (again) resigned to having to use a vice-grip or something to thread the post out, but it would be worth it. Lo and behold, the post had an allen-wrench head on the bottom and a few turns popped it right out.Add to that the nice chunky bar itself (should carry all the current I want to throw at it and then some) and the fact that the nuts that the cover screws go into are trapped so the cover goes on and off with just a screwdriver (no extra fingers and contortions to hold the nut while you get it started) and you have yourself a nicely designed product, well worth the price. I have used other bus bars elsewhere in this project and mildly regret that they weren't all these.

High quality and well made - used on my RV Lithium Battery conversion to neaten up the wiring. Definitely recommended.

I liked the quality of these products. They seem very well made and are very heavy duty. They worked as expected for my solar install.

Nothing left to say but not much to it but does it’s job.

Nice parts

Very well made

I concur with other reviewers, these are sturdy a very well made. Purchased for my sailboat because I kept adding accessories to it and I now got a winch, so yeah. These will clean things up nicely!

I ordered twice the first time it came on the hard plastic case it states m10 connection stud. I sent them back and reorderedSame thing happened but I double checked and the say m10 but actualy are M8So but confusing and a huge run around they are wrongly labeled

It did the job

Le bon matériel !
