4 Post Power Distribution Block Bus Bar with Cover - Made in The USA - 250 Amp Rating - Marine, Automotive, and Solar Wiring (5/16" - Red)

I had high hopes for these as I need a 4 post bus... I put on one wire and tightened it down. I decided to make a change so tried to remove the nut. Nut will not come off and since the bottom is plastic the head of the bolt just spins. These are junk. Buy them at your own risk.

Well made. Works well. Covers are excellent for protecting the studs from accidental shorting by bv tools or other.

So hard to tell just how big these are till you see in person.. I just got them in today during lunch break.... Yes.. that's my hot pocket.... Pizza flavor... Cooked on high for 2 min. Anyway - they are heafty feeling so far so good. After install if I remember I'll come back and update this review. Gooooo hot pocket!!

I upgraded my old bus bar with this one as I upped my amperage, and it was now necessary to go with a larger one. It was very easy to replace the old one, as the form factor and holes lined up with the old one exactly.This bus bar is high quality and can handle up to 250 amps through four 5/16 posts. There are also three screws for connecting low amperage devices allowing for a total of seven connections. That was exactly what I was needing. I now have piece of mind knowing that this bus bar will handle everything I can throw at it. No warming, secure and safe connections with protective covers for added safety.This is marine quality for long lasting performance. It is top quality and I find it to be a terrific value for the price. I give this bus bar 5 stars.

Very strong, easy to mount, small screws also included in mount base for add on devices like monitors, etc, plus covers to protect when open mounted. This was used to feed my solar inverter from my battery bank. It still allows me the option to add another future battery bank from the same terminials.

I’m calling false advertising on this one. Am I the only one that notices a striking similarity between these “made in the USA” bussbars and the China knockoffs that look identical to them. I will guarantee that these are not any different. They use the same crappy hardware and over the top lock washers that cause people to not be able to get the nut back off after tightening down. They use the exact same SS hardware and the exact same plastic piece of junk to hold the bolts. The metal is pretty thin too and what you se is what you get because there isn’t any metal hiding under the plastic. So I don’t know about 250 amps?What upsets me as a US Army Vet. is the claim that these are somehow different or made in the USA and then claim to be firefighter owned. The only way I could see this person even possibly making this claim is if they took the Chinese knockoffs and replaced them with better hardware. Then maybe it would be technically “assembled in the US”. Anyway. Don’t be fooled. The pictures are right in front of your face. They use the same screw, lock washers, housings, ss hardware, and black nylon cover caps as the Chinese ones sold on this site. You really think they’re different?I would caution against using the lock washers that come with the kit. Being that plastic is all that holds the bolts still, if it’s spins off you have an afternoon of dremel cutting ahead of you.

I installed these when I added a dual battery setup to my boat. I used a battery isolator and needed to bridge the negative connections of both batteries. I ran 1/0 cables, and used 5/16" studs. For the positive terminal block, I used it to feed the accessory circuits that already originated on the boat, which gave me a much cleaner look. The smaller screws work well for some low amp circuits. I didn't have an issue tightening the 5/16" bolts down as some did...these are held in by moulded plastic, where I wish they would have double nutted them. But they don't need much torque on them to get them tight. Just don't over-tighten or you'll strip them. Glad they were USA made as well!

I like how rugged built the bus bar is! I used these on my bass boat to isolate all my electronic accessories so I didn’t have to stack them in my battery posts. It makes it easier come winter to pull just one set of cables from my battery to pull them for storage of the boat!
