Scanstrut

<h3>About Scanstrut</h3><p>Since 1986, Scanstrut has built a reputation as one of the marine industry&apos;s most trusted names in mounting systems, power solutions, and cable management. Headquartered in Clyst St. George, Devon, UK, this independent, privately held company has spent nearly four decades engineering products that help boaters install and protect their electronics with confidence. <strong>Scanstrut&apos;s entire product line is conceived, designed, and developed in-house</strong> — a commitment to quality that has earned the company a Queen&apos;s Award for International Trade as well as numerous design and product awards over its history.</p><p>With a catalog spanning over 300 items, Scanstrut&apos;s offerings are organized across four core ranges: mounts, charge, seal, and air. Whether you&apos;re fitting out a center-console powerboat, a bluewater sailing yacht, a superyacht, or an RV, Scanstrut has engineered a solution that integrates cleanly and performs reliably in the harshest outdoor environments. The brand is trusted by major marine electronics manufacturers worldwide and has become the go-to choice for both professional installers and serious DIY boaters.</p><h3>Radar &amp; Satcom Mounting Systems</h3><p>Scanstrut&apos;s flagship <a href="/11564-scanstrut-radar-satcom-mounts-accessories-200839">Radar &amp; Satcom Mounts &amp; Accessories</a> are perhaps their most celebrated products. The iconic PowerTower series — available in aluminum, stainless steel, and composite — raises radar domes to an optimal height for clear, unobstructed performance. These mounts are compatible with radar and satcom equipment from leading brands including Garmin, Simrad, Raymarine, and Furuno, making them a universal solution for virtually any electronics suite.</p><h3>Antenna &amp; Transducer Solutions</h3><p>Solid positioning is just as critical for GPS and VHF antennas as it is for radar. Scanstrut&apos;s <a href="/200416-fixed-antenna-mounts-scanstrut-11564">Fixed Antenna Mounts</a> deliver the secure, vibration-resistant foundations needed to keep navigation antennas performing at their best in open-water conditions. Complementing these are Scanstrut&apos;s Transducers &amp; Accessories, which extend the brand&apos;s precision engineering into the underwater domain, ensuring sonar and depth-finding equipment is properly mounted and protected.</p><h3>Waterproof Power &amp; Charging</h3><p>Modern boating means keeping phones, tablets, and cameras powered up at all times. Scanstrut&apos;s range of 12V &amp; USB Connectors, Outlets, Plugs &amp; Extensions — including the popular Flip Pro series — are built specifically for the marine environment. Spring-loaded, waterproof caps protect USB-A and USB-C ports from spray and splashing, while the 12V sockets are engineered to handle the vibration and moisture that would quickly degrade standard consumer-grade hardware.</p><h3>Cable Seals &amp; Thru-Deck Fittings</h3><p>A clean, watertight installation is the hallmark of professional-grade marine electronics work, and Scanstrut&apos;s <a href="/11564-scanstrut-cable-covers-outlets-thru-deck-fittings-200229">Cable Covers, Outlets &amp; Thru-Deck Fittings</a> make it achievable for any boater. Where cables must pass through a deck or bulkhead, Scanstrut&apos;s sealing solutions create a 100% watertight passage without messy sealants or improvised solutions — preserving both the integrity of the vessel and the neatness of the installation.</p><h3>Why Choose Scanstrut?</h3><ul style="list-style:disc"><li>Nearly 40 years of specialized marine engineering expertise</li><li>In-house design team delivering consistent innovation and quality control</li><li>Compatible with virtually all major marine electronics brands</li><li>Award-winning products, including a Queen&apos;s Award for International Trade</li><li>Products engineered for powerboats, sailboats, superyachts, RVs, and more</li></ul>
