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. Their <a href="/7549-sea-dog-line-electric-horns-200351">electric horns</a> include the popular MaxBlast line, which passed rigorous 600-hour salt spray testing while meeting US Coast Guard COLREGS and ABYC standards for audible warning devices. 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.

all good so far

Great prices and very reasonable shipping costs. Used standard shipping and received the parts the next day. Parts received were what was ordered.

Overall it was good. I was looking for Neef bars for my truck, however the ones I found after entering my vehicle didn't verify that they would fit it so I didn't purchase them.

Thank You

Site is nice, wish it had more filtering options, for instance, front brakes only, or rear rotors, etc.

Straight up , seamless process

super easy, no fuss shopping. log in, pay out....DONE. Awesome.
