Founded with a singular mission to deliver electrical products capable of withstanding the harshest marine environments, Ancor has become the gold standard for boat builders, marine electricians, and automotive enthusiasts who demand uncompromising reliability in challenging conditions.</p><h3>Engineering Excellence for Extreme Environments</h3><p>What sets Ancor apart is their commitment to exceeding industry standards. Ancor Marine Grade™ wire and cable is manufactured from tinned copper stranding for maximum protection against corrosion and electrolysis. This electroplating process coats every individual strand with tin, preventing the corrosion that can compromise standard bare copper wire.

Ultra flexible (Type 3) stranding resists fatigue due to vibration and flexing. Exceeds all UL 1426, US Coast Guard Charter boat (CFR Title 46) and ABYC standards. Available in multiple gauges and a full spectrum of colors to match proper wiring protocols, these products are essential for anyone building or maintaining electrical systems in demanding applications.</p><h3>Complete Wire Management Solutions</h3><p>Our extensive product line encompasses everything you need for your next wiring project, including wire, cable, terminals, connectors, wire management products, and hand tools. Beyond wire itself, Ancor has developed a comprehensive ecosystem of complementary products. Their <a href="/7231-ancor-wire-tie-17375">wire ties</a> feature UV-resistant construction that won't become brittle in harsh sunlight, while their terminals utilize double-crimp designs for maximum strain relief and connection integrity.</p><p>For vehicle protection needs, Ancor even offers <a href="/7231-ancor-car-cover-1020">car covers</a> engineered to guard against the elements. Meanwhile, specialized components like <a href="/7231-ancor-disc-brake-rotor-1896">disc brake rotors</a> and <a href="/7231-ancor-automatic-transmission-control-solenoid-7752">automatic transmission control solenoids</a> demonstrate the brand's expanding reach into broader automotive applications.</p><h3>Trusted by Professionals, Accessible to All</h3><p>All of our products are built for the harsh marine environment and conform to industry standards. Whether you're rewiring an entire vessel, making repairs to an RV electrical system, or upgrading automotive wiring harnesses, Ancor provides the durability and performance needed for installations that last.

It was alot faster than the AutoZone.

very good I hope this product works as advertised looks like a good dye

just ordered the part that was easy and quick

I ordered a new clutch on June 12, and the item shipped the same day. Had the item on time as expected. They also beat all other retailers prices by a significant amount. Their shipping costs were also reasonable. The only issue I experienced is that it is virtually impossible to get order status from their Website if you do not have an account. Anytime I used the link provided in the order confirmation E-Mail would always return an error.

Great pricing and quick shipping. I'll be using them again for sure.

The ordering process was very simple. Also, I've searched the internet and they defiantly have the best prices.
