Manufacturer
<p>For over a century, Sea-Dog Line has stood as a cornerstone of the marine hardware industry, delivering innovative solutions that meet the demanding needs of recreational and commercial boaters. Founded in the early 1920s by entrepreneur Hans "Action" Broson Sneve, the company began with a unique sales approach—showcasing marine hardware aboard a 55-foot cruiser that sailed from Alaska to Mexico. This hands-on philosophy continues to shape Sea-Dog's commitment to producing hardware that performs reliably in the harshest saltwater environments.</p><h3>Industry-Leading Marine Hardware Manufacturing</h3><p>Based in Everett, Washington, Sea-Dog Corporation operates a 75,000-square-foot warehouse stocking over 8 million parts and runs an injection molding facility with 16 machines producing more than 17 million components annually. The company's extensive product line spans anchoring systems, deck hardware, electrical components, plumbing fittings, and lighting solutions—all engineered with marine-grade materials like stainless steel, brass, and UV-resistant polymers. Sea-Dog's recognition as a multiple-time NMDA Supplier of the Year underscores the brand's excellence in both product quality and customer service, while their on-staff ABYC-certified marine technician provides invaluable installation and technical support.</p><h3>Premium Marine Components for Every Vessel</h3><p>Sea-Dog's <a href="/7549-sea-dog-line-windshield-washers-wipers-replacement-motors-201195">windshield washers, wipers, and replacement motors</a> deliver crystal-clear visibility during inclement weather, with both manual and electric options featuring corrosion-resistant stainless steel arms and UV-stable blades designed specifically for marine windshield applications.

For fuel and water system integrity, Sea-Dog's <a href="/7549-sea-dog-line-deck-fills-200307">deck fills</a> provide secure, leak-free access points constructed from durable stainless steel with snap-in designs that resist corrosion in saltwater environments.</p><p>When maneuvering in low-light conditions, Sea-Dog's <a href="/7549-sea-dog-line-docking-lights-200335">docking lights</a> offer bright LED illumination with minimal power draw, featuring injection-molded housings that withstand impacts and temperature extremes.

As long as i recieve the part in a timely fashion this would be rated a five. Site is strange, had truck as vehicle (2000 tundra) and showed no parts, but typed in part # and they came up. Also, did not get 20% coupon code as intro stated.

You can tell customer service is important to this company. Not only were the prices lower than other places but they communicate the status of the order and shipping very well. They obviously care what people think. I was suspicious of all the positive comments but decide to try them anyways. Very happy I did and definitely plan on buying from them again.

I had been working with a salesman to purchase an exhaust. In the midst of this, something happened and the price went up. After relaying this to the salesman, he agreed to honor it at the first price. That shows a lot of character for a company that wants to please it's customers! Would definitely buy from them again!

Your website is a little clunky, but your prices are worth it :D The parts showed up on time and well packaged. I was a little freaked because I googled Autoplicity after I placed my order and saw some bad reviews online. My experience was fantastic. Keep
