Ancor 12/2 AWG Flat Duplex Cable — 100 Feet, tinned copper marine-grade with ultra-flexible vinyl jacket

Ancor Flat Duplex Cable 12/2 AWG is a 100-foot, ultra-flexible, tinned-copper marine power cable with black and red conductors for ABYC-compliant polarity and durable vinyl insulation built to withstand saltwater, oil, UV and vibration.

This 12/2 AWG flat duplex cable from Ancor is engineered for marine electrical systems where reliability, flexibility and corrosion resistance matter. Constructed from finely stranded, tinned copper and enclosed in a premium vinyl jacket, it meets stringent boat-cable standards and provides straightforward polarity identification with black and red insulated conductors. The 100-foot length gives installers ample reach for run layouts on small craft, center consoles and larger vessels.

What makes this cable suitable for marine use?

Every element is selected to resist the unique stresses of a marine environment: vibration, salt spray, chemicals and UV exposure. The fine Type 3 (Class K) stranding minimizes fatigue from repeated flexing, while tinning protects the copper from corrosion. The vinyl insulation holds flexibility at very low temperatures and resists abrasion and common contaminants.

• Tinned, multi-strand copper for corrosion resistance and conductivity
• Type 3/Class K ultra-flexible stranding to resist vibration fatigue
• Premium vinyl jacket resists salt water, oil, gasoline and UV
• Meets or exceeds UL 1426, USCG (CFR Title 46) and ABYC standards

How does the cable perform electrically and thermally?

The conductors are rated for 600 volts, and the insulation withstands substantial temperature ranges for marine installations. You can expect stable performance in both dry and wet conditions, with insulation temperature ratings that align with common onboard applications.

• Insulation rated 600 V
• 105°C maximum dry temperature rating
• 75°C wet temperature rating suitable for marine environments
• Performs across wide temperature ranges, remaining flexible to -40°F/-40°C

How does installation and maintenance benefit from this design?

The flat duplex format and color-coded conductors simplify routing and polarity identification under gunnels, through conduits and in tight bilge spaces. The outer jacket is designed for easier trimming and reliable abrasion protection, cutting down installation time and long-term wear concerns.

• Flat duplex profile for neat runs and low-profile routing
• Black and red insulation follows ABYC color conventions for clear polarity
• Jacket formulated for easy stripping and superior abrasion resistance
• Tinned strands improve connection life in corrosive conditions

What certifications and standards does this cable meet?

This cable is manufactured to exceed the most common marine electrical standards, giving installers confidence in safety and regulatory compliance. Those certifications are widely recognized in the boating industry and used as benchmarks for vessel wiring integrity.

• Exceeds UL 1426 boat cable requirements
• Complies with US Coast Guard Charter boat (CFR Title 46) requirements
• Meets ABYC (American Boat and Yacht Council) color-coding and construction guidance

Who is this for? Boat owners, marine electricians and DIY installers who need a robust, flexible power cable for DC circuits will find this Ancor 12/2 AWG flat duplex cable ideal. It’s suited for battery-to-switch panels, accessory circuits and other low-voltage wiring runs where corrosion resistance, ease of routing and regulatory compliance are priorities. Choose the 100-foot length when planning longer runs or keeping a spare on hand for repairs and upgrades.
