Beckson Marine

<h3>Beckson Marine: Seven Decades of Marine Innovation</h3><p><strong>Beckson Marine</strong> has been a cornerstone of the marine hardware industry since 1955, when the Bridgeport, Connecticut company set out to solve one of boating's most persistent problems. <a href="/7253-beckson-marine">Beckson</a> pioneered the world's first dependable, self-priming, all-plastic bilge pump — a product that would become the foundation of an entire philosophy: build it right, test it relentlessly, and make it last in the harshest environment on earth.</p><p>The insight behind that original pump was surprisingly forward-thinking. At a time when metal was the default material for marine hardware, Beckson recognized that plastics offered something metal could not: freedom from electrolysis, corrosion, and the constant maintenance burden that plagued metal thru-hull fittings. By the 1970s, the marine industry had largely caught up to what Beckson already knew, and plastic had become the standard. Beckson helped get it there — pioneering the use of rigid PVC, Lexan&reg;, polypropylene, and other advanced materials now common throughout the industry, earning more than two dozen patents along the way.</p><h3>A Product Line Built Around Life on the Water</h3><p>From that single iconic pump, Beckson grew its catalog to well over 900 items. The success of the Thirsty-Mate&reg; hand pump line created a natural need for deck-level access, which led Beckson to invent the first pop-out <a href="/7253-beckson-marine">deck plate</a> — eliminating the spanner wrenches required by traditional threaded metal models. Further refinements introduced the first self-cleaning buttress thread in screw-out deck plate designs, a feature boaters still rely on today to keep sand and grit from jamming the threads.</p><p>Beckson's <a href="/7253-beckson-marine">hatches and opening ports</a> represent what the company calls its greatest contribution to the marine industry. Years of research produced a patented line of portlights and hatches engineered to eliminate leaks, condensation, and corrosion. Available in flush, raised full-size, ventilation, and versatile stow-away configurations, Beckson hatches open a full 180 degrees and feature a rugged Slip-Clip snubbing latch for reliable, weather-tight performance. The company's Vent-O-Mate&reg; exhaust ventilator and air scoops round out the ventilation lineup, actively combating the dampness and mildew that can plague enclosed cabin spaces.</p><p>Beyond structural hardware, Beckson supplies an extensive range of <a href="/7253-beckson-marine">marine accessories</a> including boat hooks, drink and equipment holders, kayak accessories, drain plugs, and fittings. The brand's boat hooks are engineered so they won't collapse at the critical moment of docking — a real-world reliability standard that defines the Beckson approach across every product category.</p><h3>Trusted by Boat Builders and Boaters Worldwide</h3><p>Beckson's reputation extends well beyond the aftermarket. The company serves as an OEM supplier to high-quality boat builders around the world, a testament to the consistency and precision of its manufacturing. In 2016, Beckson's 4", 6", and 8" deck plates became the first certified by independent lab testing to meet or exceed ABYC H-3, NEMA 250 6P submergence, and ISO 12216 watertightness and strength standards — a milestone that underscores the company's commitment to independently verified performance.</p><p>As a privately held, family-oriented business headquartered in Bridgeport, Connecticut, Beckson has always operated with a &quot;boaters for boaters&quot; ethos. Continuous testing, refinement, and a genuine passion for life on the water have kept the brand at the forefront of marine hardware for over 70 years — and show no signs of slowing down.</p>

Great price

Great prices. Great customer services. Reasonable shipping and ship time.

Good price for great name brand car parts. AEM fuel filter very low price and new. Hope the shipping is as great as the price. :)

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.

Excellent, GREAT PRICES!
