Ancor 18/2 100ft Spool Tinned Copper Duplex Black/Red

The Ancor 18/2 100ft Spool Tinned Copper Duplex Black/Red marine electrical wire is the backbone of any reliable onboard wiring system. Whether you're rigging a center console, upgrading a cruiser's electrical backbone, or running accessory circuits from your battery bank, this dual-conductor cable is engineered to handle the demands of saltwater and freshwater environments alike. Serious anglers and boaters know that corrosion and wire degradation below deck can strand you miles from the ramp—this spool provides the dependable conductor material and protection needed to keep your navigation, lighting, and auxiliary systems running when it matters most.

Built with tinned copper conductors, the Ancor 18/2 resists oxidation and corrosion far better than bare copper, making it ideal for the harsh marine environment where moisture and salt spray accelerate degradation. The duplex configuration—two insulated conductors bundled together—simplifies installation and reduces clutter in tight engine compartments and cabin spaces. Eighteen-gauge copper delivers adequate amperage for low-to-medium power applications while remaining flexible enough to route through existing conduit and harnesses without excessive strain. The black and red color coding follows marine electrical standards, allowing quick identification of positive and negative runs during installation and future troubleshooting. One hundred feet per spool balances bulk supply with practical usability for most boat wiring projects.

Anglers upgrading livewell pumps, fish finders, trolling motors, or cabin lighting will appreciate the extra length and duplex design that eliminates the need to splice separate conductors. Boaters performing electrical system rebuilds, adding new accessory circuits, or replacing corroded original wiring benefit from ordering multiple spools to complete a project without mid-job shortages. This marine-grade wire meets the exacting standards of saltwater service and integrates seamlessly with standard marine terminals, breakers, and fuses. Stock a spool in your workshop for emergency repairs or planned upgrades—tinned copper durability ensures your electrical system won't let you down when you're out on the water.
