Solid Performance for High Power Applications
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.

High quality buss bars! Worth the money!
High quality buss bars! And yes, you get one red and one black! Both are configured as a positive buss bar, so the black one does not ground to the mounting surface. High quality, perfect for my little relay setup in my rock crawler!

Great Heavy-Duty Power Block
This 400A 12V bus bar is solidly built and works exactly as advertised. The four 3/8" studs make it easy to organize multiple high-amperage connections, and the block feels durable enough for automotive or marine setups. Installation was straightforward, and it provides a clean, reliable way to manage power distribution. My only minor gripe is that the protective cover could fit a bit more snugly. Overall, a strong and dependable choice for high-current wiring projects.

Simple to use, easy to install product!
Works great! I use this on my car to hook the subwoofer, heated mirrors, rear fog light, and some light pods onto the battery. It makes mounting all those things onto the battery a lot easier and cleaner! Make sure to run a fuse between the battery and this product to prevent a fire. Remember to also put smaller fuses post-distribution.
