Sold as a pair, these vents mount flush to the hull or deck and allow air to flow freely while the hinged clamshell cover deflects water and spray. The 316-grade stainless steel construction resists corrosion in saltwater environments and maintains a clean, professional appearance over time.\u003c\/p\u003e\u003cp\u003eThe 1-5\/8\" size is the most common clamshell vent for smaller compartments, bilge areas, and storage lockers on powerboats, sailboats, and pontoons. The heavy duty designation means a thicker shell and more robust hinge compared to standard-duty versions — a meaningful difference in high-exposure locations.\u003c\/p\u003e\u003ch3\u003ePart Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Gem Products\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e GEM-839\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heavy Duty Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Size:\u003c\/strong\u003e 1-5\/8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e Sold as a pair (2 vents)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Style:\u003c\/strong\u003e Surface \/ flush mount\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBilge compartment ventilation on powerboats and sailboats\u003c\/li\u003e\n\u003cli\u003eStorage locker and lazarette ventilation\u003c\/li\u003e\n\u003cli\u003eCabin and below-deck air circulation\u003c\/li\u003e\n\u003cli\u003ePontoon boat storage compartment venting\u003c\/li\u003e\n\u003cli\u003eAny marine application requiring a 1-5\/8\" clamshell vent opening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHeavy duty stainless steel — superior corrosion resistance in saltwater\u003c\/li\u003e\n\u003cli\u003eHinged clamshell cover deflects spray and rain while allowing airflow\u003c\/li\u003e\n\u003cli\u003e1-5\/8\" opening size — fits standard small-compartment vent cutouts\u003c\/li\u003e\n\u003cli\u003eSold as a pair — covers both sides of a compartment in one order\u003c\/li\u003e\n\u003cli\u003eClean, low-profile appearance suits most hull and deck finishes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eRelated Products\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/west-797\"\u003eFuel Vent Flush 5\/8\" 90°\u003c\/a\u003e — flush-mount fuel tank vent for 5\/8\" hose\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/seachoice-16141-stainless-steel-clam-shell-vent-1-21-32-x-1-3-4-x-7-16-50-16141\"\u003eSeachoice 16141 Stainless Steel Clam Shell Vent — 1-21\/32\"\u003c\/a\u003e — similar SS clamshell vent option\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/seachoice-16151-stainless-steel-clam-shell-vent-2-5-32-x-2-1-8-x-15-32-50-16151\"\u003eSeachoice 16151 Stainless Steel Clam Shell Vent — 2-5\/32\"\u003c\/a\u003e — larger SS clamshell vent\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/t-h-marine-clam-shell-vent-2-per-pack-232-cs1dp\"\u003eT-H Marine Clam Shell Vent (2 Per Pack)\u003c\/a\u003e — alternative clamshell vent pair\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/sea-dog-xxx-ss-midget-vent-1-5-8-354-3313601\"\u003eSea-Dog SS Midget Vent 1-5\/8\"\u003c\/a\u003e — stainless midget vent in the same size class\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eClamshell vents are one of those items that get overlooked until a compartment starts smelling or a bilge pump runs more than it should. The 1-5\/8\" heavy duty pair is the right choice for smaller bilge and storage compartments where you want a durable, corrosion-resistant vent that won't need replacing in a few seasons. The heavy duty version is worth the small price difference over standard-duty if the vent is in a high-exposure location — forward bilge, transom, or anywhere that takes regular spray. Install one on each side of the compartment for cross-ventilation; that's why they're sold as a pair.\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43564153241636,"sku":"GEM-839","price":8.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/3cf8e7fb-9ea7-485d-985a-965e57524c25.png?v=1787790133","url":"https:\/\/marisolmarine.com\/products\/gem-products-clamshell-vent-1-5-8-hd-stainless-pair","provider":"Marisol Marine Company","version":"1.0","type":"link"}
