Marine Grade Connectors

It would probably not be hard to believe that we’ve done a TON of marine wiring.  In the process, we’ve run across many connectors and terminal needs over the years and done more sample ordering, experimenting, and testing than we can remember.

But ultimately the terminals and connectors above are what our assembly guys keep on their workbenches. Top-quality connectors – the same ones we use on our high-end marine switch panels.

From a standard quick connect to a 3-way butt splice, these parts are genuine quality – not the hard to crimp, shrink and use junk you’ll find on Amazon or at the auto parts store.  Try out the difference for yourself, including many of the hard-to-find parts we’ve hand-selected above.
