Heart Horse Bus Bar Terminal Block, Power Stud Battery Junction Post 1/4" Power Distribution Positive Negative for Truck RV Boat, Dual Heavy Duty Stainless Steel DC 48V (Red)

These were just what the Doc ordered for me except for ONE thing.I got the 1/4" pair. Simple, easy, obvious how to install. Beefy enoughfor my usage which was my boat battery box.The only issue was the 4 nuts they supplied. They are THIN and madeof brass (ie: soft compared to the steel bolts they go onto). There are only3 threads on the nut. If you crank down on it to get it really tight,the threads on the nut strip. A minor irritant was that the nuts are so skinny,and the bolt is long enough, that you need a 13mm deep socket to tighten itdown unless you have a half inch high "pile" of connectors on the post.And remember: Be gentle when tightening or the nut threads will strip out.(I ended up getting 4 normal SS nuts at the HW store and replaced them all).

The plastic bracket is soft and the hold-down screw holes are flimsy.Edit: revised downward after working with more of these. The plastic is so soft it's impossible to put anything but the lightest pressure on these, but the terminal studs are 5/16", implying suitability for larger cables. It's not. I broke several even taking reasonable care not to. I ended up replacing them with a Blue Sea bus bar (their item # 2020, Amazon item # B00H8L5AKE) which is a little larger and MUCH stronger. The cost is higher, of course, but not exorbitant.

Cracked trying to hand screw it to soft pine. Inferior material for high amperage applications. Major fire hazard if this were to have broke after the wiring was attached.

Worked great for adding more wiring to my old truck.The link in the middle can be eliminated for switched and hot battery buss if desired.Eliminating link would give you a post for pos. and neg. such as the two leads on an electric cooling fan.

I used a pair of these to install an easy disconnect for the water pump in my travel trailer. Instead of having to rewire the next time I have to replace the pump, I just unscrew the terminal and swap out the part. Only wiring will be crimping the terminal rings to the pump wires, then screw it back on. Great purchase!

The terminal blocks themselves are fine. Sturdy and fit for use. But the nuts supplied with them are unusually thin and soft and stripped when I attempted to tighten them down. Battery cables are stiff and force is need to secure them, especially if you are connecting multiple lugs to a single post. So if you want to use these plan on supplying your own standard nuts.

Happy with these. Made for a clean and organized and safe setup of my DIY battery box. Hardware seems good quality.

Needed to solve a problem in my solar panel system. Needed to gang 2 ground lines in from different panels. This did exactly that. And did it well. Seems amazingly well made and sturdy. Super easy to use and straightforward.

Need these terminals to rewire my RV for a lithium battery upgrade. The lock washers provided are 3/8", a little large on the 5/16' posts.

Plastic broke on one when installing. Still works
