Rated at 50 pounds of force, it is sized for medium-weight hatch lids and extends to 12 inches overall with an 8.6 inch compressed length, making it a straightforward fit for hatch openings sized to match that travel range. The stainless steel housing and rod resist corrosion from saltwater spray and humid marine environments, so the strut continues to extend and retract smoothly season after season rather than seizing up the way an unprotected steel spring can. Installation is simple: the gas spring mounts between the hatch and the surrounding frame or coaming, using the same basic ball-stud or bracket mounting common to boat hatch struts, and once in place it lifts and holds the hatch at its open position automatically. It is a good match for anyone replacing a worn-out, weak, or leaking hatch strut, or for anyone building a new hatch, deck box, or storage lid that needs a reliable prop. At just under 0.4 pounds, it adds minimal weight to the hatch assembly while providing consistent, repeatable support.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Attwood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e ST35-50-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Gas spring \/ hatch support strut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForce Rating:\u003c\/strong\u003e 50 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Length:\u003c\/strong\u003e 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompressed Length:\u003c\/strong\u003e 8.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.3854 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 022697355058\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Boat hatches and hatch adjusters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the force rating of the Attwood ST35-50-5 gas spring?\u003c\/strong\u003e It is rated at 50 pounds of force, which is the amount of support the Attwood ST35-50-5 provides to hold a hatch or lid in the open position.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is this gas spring made from?\u003c\/strong\u003e The Attwood ST35-50-5 is made from stainless steel, chosen for its resistance to corrosion in saltwater and humid marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the extended and compressed lengths of this strut?\u003c\/strong\u003e The ST35-50-5 extends to 12 inches overall and has a compressed length of 8.6 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this gas spring work for a heavy deck hatch?\u003c\/strong\u003e At a 50 pound force rating, the Attwood ST35-50-5 is sized for medium-weight hatches and lids rather than very heavy deck hatches; check the weight of your hatch against this rating before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the ST35-50-5 weigh?\u003c\/strong\u003e This Attwood gas spring weighs 0.3854 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this gas spring suitable for saltwater use?\u003c\/strong\u003e Yes, the stainless steel construction of the Attwood ST35-50-5 is designed to hold up against saltwater spray and marine humidity without corroding.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this gas spring replace a weak or worn-out hatch strut?\u003c\/strong\u003e Yes, the ST35-50-5 is commonly used to replace a hatch gas spring that has lost pressure or seized, restoring the hatch's ability to stay open on its own.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this part?\u003c\/strong\u003e The Attwood ST35-50-5 stainless steel gas spring carries UPC 022697355058.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the hatch stay open on its own with this strut installed?\u003c\/strong\u003e Yes, the ST35-50-5 is a self-supporting gas spring, meaning it holds the hatch open at full extension without a separate prop or latch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of products is this gas spring used on?\u003c\/strong\u003e The Attwood ST35-50-5 is used on boat hatches, deck lids, and storage compartment covers that need a strut to hold them open.\u003c\/p\u003e","brand":"Attwood","offers":[{"title":"Default Title","offer_id":48989679419611,"sku":"ATT-ST35-50-5","price":35.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/i_1055c1e0-83d3-4950-af67-e863035c8f2c.jpg?v=1785349183","url":"https:\/\/www.goodvibesmarina.com\/products\/attwood-st35-50-5-stainless-steel-gas-spring-12-in-extended-x-8-6-in-stroke-50-lb-force-boat-hatch-lift-support-strut","provider":"Good Vibes Marina","version":"1.0","type":"link"}
