Ancor 121110 Marine Grade Tinned Copper Flat Duplex Cable – 10/2 AWG – 100 ft Roll

The Ancor 121110 Flat Duplex Cable is a premium 10/2 AWG marine-grade tinned copper cable designed to deliver dependable power transmission in demanding marine environments. Featuring Type 3 ultra-flexible tinned copper stranding, this cable provides superior protection against corrosion, electrolysis, vibration, and fatigue, making it the preferred choice for professional marine electricians and boat builders.

The cable's flat white outer jacket allows for easy routing and installation while offering excellent abrasion resistance. Inside, the red and black conductors are colour-coded to ABYC standards, simplifying identification and reducing installation errors.

Constructed with premium vinyl insulation, the Ancor 121110 remains flexible even in extreme cold and resists salt water, battery acid, oil, gasoline, UV exposure, and abrasion. Rated for 600 volts, 105°C (221°F) dry, and 75°C (167°F) wet, it exceeds UL 1426, ABYC, and U.S. Coast Guard Charter Boat (CFR Title 46) requirements.

Whether wiring battery circuits, DC distribution panels, lighting, pumps, navigation equipment, or other onboard electrical systems, the Ancor 121110 delivers long-lasting, professional-grade performance.

TECH tip

Wire Flexibility Explained

Wire flexibility is influenced by two major factors: Wire strand sized jacket hardness.

Wire strand size has the largest impact on overall wire flexibility.

As individual wire strand size decreases, wire flexibility increases. For boat cable, UL 1426 requires at least 19 individual strands for cables 16 AWG and larger, Ancor wire uses type 3 stranding which consists of  individual 30 AWG (0.010”) strands, regardless of the wire gauge .Ancor’s 16 AWG wire, consists of 26 individual strands, while the 4/0 AWG wire consists of 2,109 individual strands

jacket hardness is most commonly measured by durometer, with lower measurements reflecting a more flexible material. Ancor wire measures 7 points lower than competitive product (on a scale of 1-100), resulting in a more flexible product.
