Manufacturer

Ancor

<p>For over 40 years, Ancor has been the industry leader for high-quality tinned copper Marine Grade® wire and cable. 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. The brand's reputation rests on delivering consistent quality across every product category, ensuring that whether you're purchasing 100 feet of wire or a single connector, you're getting the same commitment to excellence that has defined Ancor for more than four decades.</p>

Great prices

WOW.. I ordered my liners very earlier in the morning on January 31st and I received them the very next day.They also had the best price and cheapest shipping rates I could find.

So far so good

Best product &amp; shipping prices found! Thanks! We look forward to doing more business with Autoplicity.

Check out was easy

Bought a new air intake for my Ford Raptor... Got it in the time they said id get it and for a great price too ...had to call a few times to see the status because it came from the manufacturer wasn't really a big issue customer service was very helpful all the times I talked to them very very happy with my new intake and will be glad to reccommend or use autoplicity again

great service and fast shipping and the best prices by far

great price

I was able to place the order very quickly. Also, you had the parts in stock, and every other supplier I contacted would have had to special order the parts from the manufacturer. Thank you.

Easy to use

Easy and fast!

I bought 2 pairs of Stainless Steel polished 12x16 mud flaps. I looked at quite a few mud flaps for my Escalade EXT, and these were the only ones I could find that were not plastic or rubber. They are excellent, heavy duty, polished stainless flaps; and mounting hardware was included. They were well packed, shipped fast and at a very reasonable amount. Best of all they were $26.00 cheaper a pair. So I saved $52.00, got fast delivery, and got a very nice product.....Thank you Autoplicity; definitely saved in my favorites....Bill in Pittsburgh, Pa.

Easy to do business with BEST PRICE anywhere!! Shipped and arrived quickly
