Gas springs like this one use a sealed, pressurized cylinder to counterbalance the weight of a hinged hatch, letting it lift with light effort and stay open on its own instead of slamming shut or requiring a separate prop rod. Because the housing and rod are stainless steel, this gas spring is built to hold up in the wet, salt-exposed conditions typical of a marine hatch, locker lid, or storage compartment application.\u003c\/p\u003e\u003cp\u003eThis unit measures 10 x 7 inches and is rated for 20 lb of extend force, and it is sold under Attwood part number ST30-20-5. It is a compact, lightweight component at 0.3885 pounds, making it easy to handle during installation or replacement on a boat hatch, engine hatch, or storage lid where a controlled, self-supporting lift is needed.\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 ST30-20-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Gas Spring (Hatch Adjuster)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension:\u003c\/strong\u003e 10 x 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForce Rating:\u003c\/strong\u003e 20 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.3885 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 022697302052\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Boat Hatches and Adjusters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Attwood ST30-20-5 used for?\u003c\/strong\u003e It is a stainless steel gas spring designed to hold a boat hatch, lid, or access panel open, using internal gas pressure to counterbalance the hatch weight so it lifts easily and stays open without a prop rod.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the ST30-20-5 gas spring made from?\u003c\/strong\u003e The Attwood ST30-20-5 is made of stainless steel, chosen for its resistance to corrosion in wet and salt-exposed marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much force does this gas spring provide?\u003c\/strong\u003e The ST30-20-5 is rated at 20 lb of force.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Attwood ST30-20-5?\u003c\/strong\u003e This gas spring measures 10 x 7 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the ST30-20-5 weigh?\u003c\/strong\u003e 0.3885 pounds is the listed weight for the Attwood ST30-20-5 gas spring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this gas spring work on a hatch that currently uses a prop rod?\u003c\/strong\u003e The ST30-20-5 is intended to replace a manual prop rod with a self-supporting stainless steel gas spring rated for 20 lb of lift force, though the buyer should confirm the required force rating and mounting length match their hatch before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Attwood ST30-20-5 genuine Attwood, and not a generic substitute?\u003c\/strong\u003e Yes, ST30-20-5 is the Attwood manufacturer part number for this stainless steel gas spring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Attwood ST30-20-5 gas spring?\u003c\/strong\u003e The UPC for this product is 022697302052.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the ST30-20-5 be used outside of boat hatch applications?\u003c\/strong\u003e It is categorized as a boat hatch and adjuster component, so it is intended for marine hatch, lid, and access panel applications rather than general automotive or household use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the stainless steel construction affect the gas spring's durability?\u003c\/strong\u003e Yes, the stainless steel housing and rod on the ST30-20-5 are intended to resist the corrosion that a marine hatch gas spring is regularly exposed to, compared to a plated steel alternative.\u003c\/p\u003e","brand":"Attwood","offers":[{"title":"Default Title","offer_id":48989678239963,"sku":"ATT-ST30-20-5","price":32.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/i_1f7af954-2e7a-49b8-b785-792d5e04758e.jpg?v=1785349178","url":"https:\/\/www.goodvibesmarina.com\/products\/attwood-st30-20-5-stainless-steel-gas-spring-20-lb-force-marine-hatch-lift-support-strut","provider":"Good Vibes Marina","version":"1.0","type":"link"}
