Bomar

<h3>Bomar: The Industry Standard in Marine Hatches &amp; Deck Hardware</h3><p><strong>Bomar</strong> has spent more than seven decades earning its reputation as one of the world's foremost manufacturers of marine-grade hatches, deck plates, and related hardware. A division of Pompanette, LLC and headquartered in New Hampshire, Bomar operates a state-of-the-art facility where every product is engineered and assembled in the USA — from raw aluminum extrusion to finished, field-tested component. Boat builders, commercial operators, and OEMs across the globe have long relied on Bomar's commitment to precision craftsmanship and corrosion-resistant materials.</p><h3>Built in America, Trusted Worldwide</h3><p>Bomar's manufacturing process is entirely in-house, leveraging advanced CNC machining, aluminum casting, routing, laser cutting, powder coating, and anodizing — all under one roof. This end-to-end control means tighter tolerances, shorter lead times, and consistent quality across every production run. Whether it's a custom build for a fleet of patrol vessels or a standard replacement for a recreational cruiser, Bomar brings the same engineering rigor to every order.</p><p>The brand's product range centers on marine closures — the category of components that keep vessels watertight, ventilated, and safely accessible. Their <a href="/7270-bomar-hatches-200519">hatches</a> span a wide spectrum of series and profiles, from low-profile extruded aluminum designs ideal for modern sportfishers to heavy-duty cast aluminum models built for commercial and offshore applications. Frames are constructed from 6061 extruded aluminum or Almag-35 cast aluminum-magnesium alloy, and lenses are typically polycarbonate acrylic chosen for UV resistance and clarity in harsh salt-air environments.</p><h3>Access Solutions for Every Vessel</h3><p>Below-deck access is critical on any boat, and Bomar's lineup of <a href="/7270-bomar-accessutility-hatches-200061">access and utility hatches</a> delivers secure, low-profile entry to storage compartments, engine rooms, and baitwells. These hatches are engineered to be non-skid, watertight, and easy to operate even in challenging sea conditions — a combination that has made them a top specification choice among professional boat builders for decades.</p><p>Supporting the full hatch ecosystem is an equally robust selection of <a href="/7270-bomar-hatch-hardware-200516">hatch hardware</a>. Bomar manufactures replacement gaskets, dogs, handles, lenses, and fasteners using 316L marine-grade stainless steel — a material prized for its exceptional resistance to rust and saltwater corrosion. This commitment to a complete parts ecosystem means owners can maintain and restore Bomar hatches for the long term rather than replacing them prematurely.</p><h3>Deck Plates Built to Last</h3><p>Rounding out the lineup, Bomar's <a href="/7270-bomar-deck-plates-covers-200311">deck plates and covers</a> — also available as <a href="/46092-marine-deck-plate-bomar-7270">marine deck plates</a> — protect vital below-deck systems while standing up to UV exposure, impact, and saltwater immersion. Options range from molded polypropylene press-in lids for light-duty recreational applications to commercial-grade cast aluminum plates with locking T-handles for high-load, high-traffic decks. Every configuration is designed to maintain long-term deck integrity without demanding constant maintenance.</p><p>From the recreational weekend sailor to the commercial shipyard manager, Bomar's depth of product, American manufacturing heritage, and engineering expertise make it one of the most trusted names in marine deck hardware available today.</p>
