<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.
