  • BUILT BETTER - You take pride in your project, we take pride in our product. We use copper, not brass, for improved conductivity and corrosion resistance.  And the box is heavy-gauge nylon, not cheap plastic, for better heat resistance and longevity.
  • A COMPLETE KIT - Our busbar includes all of the seals, terminals and mounting bolts you'll need to get the job done. We even include a 2' 4 AWG power wire; because there’s nothing worse than missing that one small part you need to finish a project!
  • BUILD WITHOUT BARRIERS - Your equipment should never hold you back; and these junction blocks don't. With AC/DC Compatibility, carrying a 300V AC & 48V DC rating that supports up to 150A at 32V DC per bus, they are built to make your plans possible.

  • YOU'RE COVERED - What's the first thing that always breaks on a busbar? The cover. They're usually thin, rigid, and brittle. Not these covers. Our covers are flexible, flame-resistant, and aren't held on by tiny, breakable clips or easy to lose nuts.
