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!

heat shrink cable lugs

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.

20 Oct 20232/0 Welding/Battery Cable with M8-5/16" lugs (4ft Red + 4ft Black). I got exactly what I ordered. I read some reviews about bad crimping jobs....so I held the cables and (with pliers) twisted the lugs more than 180 degrees.... solid crimp ! I also pulled on it and it obviously was fine. So far I'm still a satisfied customer. Although...the lugs weren't exactly even with each other, they were close enough to practically mirror each other. I'm still fine with that. Cable specs were printed clearly on both cables. Thank you Amazon employees/drivers and WindyNation ! !
