    Cables worked great to connect two 12 volt marine together. Not sure if gauge is right since I dont have a example or micrometer.

    Nice crimps and good grade cabling

    These cables have a nice flexibility to them so routing is easy. I’ve used other cables that were so stiff they were extremely difficult to route.

    Despite being thicker than the 6-gauge cables I replaced them with, they are quite flexible. Shrink-fit insulation at the terminal ends was a nice surprise too. I used these 4 cables to replace my old 3 cables since I needed some more cable slack between my battery and winch relay for my ATV. WELL DONE!

Pure Copper Tin Coated Cable Lugs

Heavy Duty

WindyNation"s pure copper tin-coated cable lugs are heavy-duty, pure copper, and are ideal for marine and humid environments because the tin coating protects the copper cable lug from corrosion and oxidation. If you need cable lugs for an outdoor installation on your RV, boat, car, truck, golf cart, off-grid wind, or solar installation, then WindyNation"s tinned lugs are your go-to choice!

Splice

Cables are precisely cut and stripped on automated robotic cable processing machines.

Crimp

Cable lugs are attached using a 6 ton pneumatic crimper with custom dies, resulting in an ultra-strong, non-removable crimp.

Insulate

After crimping, polyolefin heat shrink tubing is applied to eliminate the possibility of moisture or chemicals penetrating into the lug/cable interface.
