Marine Bus Bar 12V 150A 1/4" Stud Pure Copper Power Distribution Block, 12 Volt DC Battery Busbar, Automotive Buss Bar 12v for Car, Boat and Solar Wiring (Black+Red)

I used this paired bus bar in a portable trailer tester that I am building. They worked great for my application. I removed the bolts that were sticking thru both covers. Both covers snap on the bus bars but I wrapped the red one with red electrical tape to help hold the cover on so hopefully nothing will get under the cover to short out. Both sides of the covers are open for the wires to have access to the bar screws. I didn't wrap the black bus bar since it is being used for the negative connections. I probably over torqued the screws on the bus bars which I didn't strip out any of the threaded holes. The bus bars have double rows of screws but I used only one row. These bus bars were the size I was looking for. I recommend these bus bars.

Perfect for small spaces and small connectors, make sure you pay attention to the sizes you need but for me it was perfect. the added covers are a great addition

Works well.

Quality is a little sub par when compared to Blue Sea, but it is a product I will install. I bought this looking for a more compact/dense bus bar than Blue Sea sells, ideally with only a single large stud - the way this one comes is a good form factor. Quality wise specifically, the main stud is loose and is secured with a nut on the top, and then another nut on that stud actually secures your wire lug that feeds it. The plastic is a little cheap, screws are a little cheap, again, as compared to Blue Sea (which is a high-quality brand).

I ordered this to connect all my ground wires for my boat electronics. First it is a well machined grounding bus bar. There are about ten to twelve grounding screws that give you ample space to connect your wires via a ring terminal with a solid connection. I really like the cover and rubber cap to cover the post ! It is all chromed a d seen ws well-made and machined to perfection. If you are thinking of getting one, get this one, you will be happy with it!

Works well, great product

Works as expected. However, I didn’t receive all that was advertised. Terminal covers were not included. Terminal ends not included. Wasn’t worth returning. Other than the items listed, worked well. Installed in a Ranger bass boat.

These are some heavy duty bus bars! Somehow I didn't picture how heavy duty it is with a 1/4" stud. I didn't use them yet, a bit overkill for my project.
