  • Great product
Size: 5/16”
These Buss bars are great! They installed easily and have connections for 5/16" wire lugs and also for smaller Guage wire lugs with a screw. I am using these busses for a dual battery system in my boat.

  • Excellent quality
Size: 5/16”
Perfect for car audio enthusiast. Rugged quality, I have no fears of anything coming loose or dropped voltage. I did tidy this up and added the shield for the ANL, but you get the point.

  • Marine life saver!
Size: 5/16" - Black
I needed this for my pontoon that had way too many connections to the batteries. This helped clean up my electrical area and functions way better than stacking connections. Easy to install!

  • Good for solar
Size: 5/16”
Used these in my solar installation. Looked all over for a distribution bar that could handle 5/16 as well as 3/8ths. I wish this thing could do all 5/16ths lugs so it would be able to handle any size lugs on the cables. But it is well made and I appreciate the top cover plate as an added safety measure. Good quality materials and workmanship. ... show more

  • Solid busbar
Size: 3/8”
I do a lot of electrical installs in trailers and small vehicles and this is one of the more well-built bus bars that I have purchased. Yes the case and mounting is plastic and a drawback is they do not supply you with mounting hardware which I would highly suggest the company to. Time will test the durability of the plastic housing but so far I have had zero issues with it done some testing and zero heat buildup like you get with some of these other cheap bus bars.. I would recommend that the company upgrade to a copper bus to eliminate any and all chance possible resistance or galvanic corrosion over time especially in more moisture prone environments. But it is extremely hard to find copper-based bus bars these days because copper is soft and a company's Sole Purpose to design a very durable device.. I will revisit this after I have thoroughly tested it. ... show more
