This is a big power distribution block. If you need a big one with multiple studs this is a great option the cover caps are nice as well.

I bought the set of red and black but ended up only needing the red block for my application. I installed it under the hood of my truck to connect some high amperage accessories. It was easy to hard mount and get wired up and then I coated all the metal components with some dielectric grease to prevent corrosion. Time will tell how durable it really is but based on the install I don't have any concerns at this point.

I've been using the bus bar in my custom 24V power bank, which runs at 100 amps, and it works like a charm. The bus bar handles the high current effortlessly, ensuring stable power distribution across my setup. The construction feels robust, and the 3/8" studs provide a secure connection for my cables.One feature I particularly appreciate is the cover, which adds an extra layer of safety by protecting the terminals from accidental contact. This is especially important in high-power applications where safety is a priority. The installation was straightforward, and it integrates well with my existing components. I haven’t encountered any issues with overheating or instability, which speaks to its quality and reliability.The only minor downside is that the cover can be a bit tricky to snap on and off, but once it's in place, it stays secure. This bus bar is an excellent choice for anyone needing a reliable power distribution solution for automotive, marine, or custom power setups. It delivers solid performance and peace of mind, even under demanding conditions.

Product and hardware is nice and can handle some torque on the lugs. Love the small Philips connectors for smaller wires but they are positioned perfectly in line with the plastic cover pieces. I ended up cutting off mine to make it fit, but it just seems like a oversight on the design.

Redid my solar setup and picked up these bus bars, they are very durable and heavy duty, I thought the pricing was a bit high at first but once I held them in my hand I was glad I picked these ones.

Great busbar. Worked as advertised. Seemed to be very decent quality. I would buy this brand again.

It says 250A can pass through this bus bar. Probably. But would you do that without monitoring the heat and temperatures? I'd hope not. Blue Sea Systems, for example, uses tin-plated copper and stainless steel studs. This way nothing will catch on fire and if you're using this on a boat or around ignitable objects that's wise. I'd trust this with 175A, I guess. Which is good enough for most people's requirements. Don't get me wrong. This is good stuff. But it's definitely not professional grade. If you're passing a lot of juice through it you're taking your chances. It looks really good. It looks very high quality. It's an excellent alternative for people who are too cheap to pay a little extra for safety.
