VERY NICE cable management item that can handle high current loads!
Very nice buss bar that does a great job with power delivery. The ONLY down side is that the spots where cmall screws are require the divider ears on the cover to be trimmed for clearance. Oh, and it does NOT come with any nut/bolt assemblies or self tapping screws to mount it down. So expect to have to purchase those before mounting this.

Good BUSS Bar
I quickly wired my sound system first time around and decided to clean the wiring up while I was replacing my fuel pump on my vehicle. I opted to get these because I didn’t like how limited you where when using a distribution block and I didn’t like how you needed an Allen head just to secure the wires. With these bus bars, I was able to manage my wires and clean them up using 3/8 copper lugs. I was going for a clean, hidden setup and managed to pull it off. Wired 2 amps with fuses and no problems so far. I also used some antiseize on the bolts as I heard they tend to seize. Would definitely recommend tho!

Low voltage requires high amperage for equivalent power.
Well built. Robust. Safety cover. Good product.

Mostly great, threads will seize without some lube
Nice design, well built, but since both the male threads on the studs and female nut threads are the same stainless alloy material, they will seize and bind if installed dry. Using some di-electric silicone or anti-seize grease on the threads prior to fastening cables will save you some major frustration. Also, the flat washer diameter is almost too large, and prevents the washers from sitting flat on top of the lugs when tightening.

Good for electric reels
I was looking for a power plug to use with my electric reels for rock cod fishing, then I came across this thinking it would be perfect for it. It's tight but it will do the job. The electric reel clips into the terminals. This works way better than connecting directly to the boat battery. The plastic cover keeps most of the salt water out. I've been using it for 2 months now. I haven't seen any corrosion yet.

Heavy Duty
I installed these power blocks in my bass boat to get rid of the cluster of wires that I have to hook to my batteries. Hooked my aerator, bilge pumps, onboard lighting and accessories on it now only have 2 battery cables hanging there much cleaner and easier to hook up. Also have the front trolling motor hooked into it as well blocks are heavy duty 5/16 studs on it and a nice plastic cover as well only thing is I wish the covers were solid on top which would make them pretty water tight just put some same color electrical tape across them {good purchase}

Great Product
This distribution block worked just as I needed it to. Everything is good quality. I dropped it as I was installing it (clumsy oaf) and feared it cracked but the bar was fine. There's a tiny chip in the cover, but it's not an issue for me. The provided hardware is good and the nuts tightened easily with no indication of the studs turning.

The only place I could get this product it is well made and strong ideal for 12 volt electronics eg power boards in campers and 4x4 for dual battery systems and inverters that need heavy duty cables .

I utilized this product with my 12-volt solar panel system in my RV. The items are well constructed and feature high-quality terminals. They enhanced the appearance of my electrical project, giving it a professional finish. While they are somewhat on the pricier side, I believe they are worth the investment.

Well made. Does the job. Physically bigger than expected - showing size would have been helpful.
