It extends to 10 inches with a compressed length of 7 inches, giving a working stroke of 3 inches, and is rated for a 20 pound lift force, so it is sized for lighter hatches and lids rather than heavy compartment covers. The spring uses end fittings of 15 mm and 6 mm diameter at its two ends, allowing it to connect to mounting hardware sized for either fitting. Construction is plastic, keeping the unit lightweight and resistant to the corrosion that can affect metal struts in a marine environment. Each unit is sold individually. The 321422-1 is part of the Sea-Dog lift spring lineup, which spans a range of extended lengths and lift force ratings, so buyers should confirm this exact part number, extended length, and lift force match the hatch or panel being fitted before ordering. Typical applications include boat hatches, storage lids, and other hinged panels that need to be propped open smoothly and held in position without a separate prop rod or latch.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 321422-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLift Force:\u003c\/strong\u003e 20 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Length:\u003c\/strong\u003e 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompressed Length:\u003c\/strong\u003e 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke Length:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Fitting Diameter (End 1):\u003c\/strong\u003e 15 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Fitting Diameter (End 2):\u003c\/strong\u003e 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.256 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1 each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514321778\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the lift force rating of the Sea-Dog 321422-1?\u003c\/strong\u003e The 321422-1 is rated for 20 pounds of lift force, meaning it is sized to hold hatches or panels in that weight range open without slamming shut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long is this gas lift spring when fully extended?\u003c\/strong\u003e It extends to 10 inches and compresses down to 7 inches, giving a working stroke of 3 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size are the end fittings on the 321422-1?\u003c\/strong\u003e One end fitting measures 15 mm in diameter and the other measures 6 mm, so mounting hardware should match these two sizes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this lift spring made of?\u003c\/strong\u003e The Sea-Dog 321422-1 is made of plastic, which keeps it lightweight and resistant to corrosion in a marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 321422-1 weigh?\u003c\/strong\u003e This gas lift spring weighs 0.256 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many lift springs come in a package?\u003c\/strong\u003e The Sea-Dog 321422-1 is packaged and sold as 1 each, a single lift spring per unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 321422-1 fit any hatch or lid?\u003c\/strong\u003e Fit depends on matching the 10 inch extended length, 3 inch stroke, and 20 pound lift force to the hatch or panel being supported; Sea-Dog offers other lift springs in different lengths and lift force ratings for larger or smaller applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 321422-1 suitable for heavier hatches?\u003c\/strong\u003e It is rated for 20 pounds of lift force, so heavier hatches or covers would need a Sea-Dog lift spring with a higher lift force rating instead.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this Sea-Dog lift spring?\u003c\/strong\u003e The UPC for the Sea-Dog 321422-1 gas filled lift spring is 035514321778.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 321422-1 need any special tools to install?\u003c\/strong\u003e It mounts using its two end fittings (15 mm and 6 mm diameter), the same way as other gas lift springs, connecting to ball studs or brackets sized to match those fittings.\u003c\/p\u003e","brand":"Sea-Dog","offers":[{"title":"Default Title","offer_id":48988650668251,"sku":"S-D-321422-1","price":20.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/7982.jpg?v=1784424827","url":"https:\/\/www.goodvibesmarina.com\/products\/sea-dog-321422-1-gas-filled-lift-spring-10-in-20-lb-force-for-boat-hatches-lockers-and-adjusters","provider":"Good Vibes Marina","version":"1.0","type":"link"}
