Sea-Dog Line

<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.

i need this part A.S.A.P

Im really pleased with the order process and will be ordering from them again

Great Price, item descriptions could be improved to be clearer.

Web site is very easy to follow or use. I'm thinking of finding other parts here. The battery has been delivered so quickly. It'd be better to see the order status changed from processing to shipping (or something) to know that it actually was shipped. Bu

Easy and fast, can't beat that with a stick. It even arrived a day earlier than indicated. What else can I ask for. The install was really smooth and really did only take me about an hour. However, I did have access to a lift because a friend of mine owns

So far so good no problems encountered

good shopping experience

best price, appreciate shipping discount

Great deals and excellent prices, fast shipping.

Prompt order processing and shipping, the item I received came in good condition and I am eager to get it installed on my car. Over the phone customer support was prompt and polite, I would order from them again.

I ordered a rear sway bar for my MINI Cooper on Sunday and it was at my door on Wednesday! Autoplicity had the absolute cheapest price for this bar and I was very impressed with the shipping speed. I would definitely recommend them to my friends!
