<h3>About Perko: Over a Century of American Marine Craftsmanship</h3><p><strong>Perko</strong> is one of the most storied names in the marine industry. <a href="/7492-perko">Browse the full Perko catalog</a> and you'll quickly understand why: this family-owned, Miami-based manufacturer has been building hardware that boaters trust since its founding in 1907 as F. Persky &amp; Co. in Brooklyn, New York. What started as handcrafted navigation lights and ventilators fabricated from brass, copper, and galvanized steel has grown into a product line of more than 1,000 individual items — all rooted in the same hands-on craftsmanship that defined the company from day one.</p><p>The Perko trademark, registered in 1922, became synonymous with quality long before &quot;quality assurance&quot; was a buzzword. Today, the company holds an ISO 9001:2015 certification and remains one of the very few domestic marine manufacturers to produce die-cast bronze parts in-house — a process recognized across the industry for strength, uniformity, and long service life. Raw materials including sheet metal, aluminum, bronze, and zinc are sourced from American suppliers, and nearly all manufacturing — from chrome plating and CNC machining to injection molding and robotic grinding — is handled under one roof in North Miami, Florida.</p><h3>What Perko Makes</h3><p>Perko's catalog spans the full spectrum of marine hardware needs. Their <a href="/7492-perko-mastheadall-around-lights-with-removable-telescoping-bases-200666">masthead and all-around navigation lights</a> remain a flagship product category, with both LED and incandescent options designed to meet U.S. Coast Guard requirements. For port and starboard visibility, Perko's <a href="/7492-perko-side-lights-200949">side lights</a> are a go-to for recreational and commercial boaters alike. On the electrical side, Perko's <a href="/7492-perko-battery-switch-12204">battery switches</a> — including their iconic bronze selector switches — are found on vessels of all types and sizes.</p><p>Perko's deck hardware lineup is equally comprehensive. Their <a href="/7492-perko-door-latches-200339">door latches</a> combine functional reliability with classic marine aesthetics, crafted from materials that resist corrosion in harsh saltwater environments. And when it comes to refueling and fluid management, Perko's <a href="/7492-perko-deck-fills-200307">deck fills</a> — available in EPA-compliant sealed configurations for gasoline, diesel, water, and waste — round out a complete onboard hardware solution.</p><h3>Why Boaters Choose Perko</h3><ul style="list-style:disc"><li><strong>Made in the USA:</strong> Nearly all products are manufactured in North Miami, FL, with American-sourced raw materials.</li><li><strong>Family heritage:</strong> Now in its fifth generation of family ownership, Perko brings continuity of quality to every product.</li><li><strong>Breadth of catalog:</strong> From navigation lights and battery switches to latches, deck fills, searchlights, and fuel system components — one brand covers your whole boat.</li><li><strong>Industry certifications:</strong> ISO 9001:2015 certified, reflecting a company-wide commitment to manufacturing excellence.</li><li><strong>Proven track record:</strong> Trusted by OEM boatbuilders, commercial shipyards, and weekend boaters for well over a century.</li></ul><p>Whether you're outfitting a new build, replacing aging hardware, or simply upgrading to LED lighting, Perko delivers the quality and reliability that serious mariners demand.</p>
