    5.0 out of 5 stars SOLID!

They're easy to mount on the wall, and I love how the punch outs slide out so that you can put them back in, ie removing them isn't permanent. I'm using mine with 0/4 lugs, no issues or complaints. Make sure you properly torque everything down with a torque wrench! If you don't have one, I'd recommend this one (make sure you get the right size for your sockets): amzn.to/3ZtlBpd

    Just what I ordered. Good quality

    5.0 out of 5 stars Well Designed and Built Bus Bar

    E.L. · July 9, 2024

    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.

    K. · July 9, 2024

    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.
