{"product_id":"qbp904531","title":"Attwood Marine Ni-Slide Hatch Support Gas Spring, 36.30 in Extended, 21.10 in Compressed, 15.20 in Stroke, 13mm Socket","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Attwood Marine Ni-Slide Series is a gas spring range for boat hatches, locker lids, and other lift-support applications where the spring length, socket style, and output force need to match the existing hardware. This configuration uses a 36.30 inch extended length, 21.10 inch compressed length, 15.20 inch stroke, and 13 mm socket end type, giving buyers clear fit points before replacing an old support.\u003c\/p\u003e\u003cp\u003eThe Ni-Slide rod coating helps with corrosion resistance in saltwater areas, and the 10 mm rod by 22 mm cylinder sizing matches the SL29 gas spring format. It is a practical replacement choice when a hatch or lid needs controlled lift assistance without changing the surrounding boat hardware.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e36.30 inch extended length, 21.10 inch compressed length, and 15.20 inch stroke for matching existing hatch support geometry.\u003c\/li\u003e\n\u003cli\u003e13 mm socket end type for use with compatible ball-stud style mounting points.\u003c\/li\u003e\n\u003cli\u003eOutput force options from 30 lb to 180 lb across the range, allowing the spring force to be matched to the weight and leverage of the hatch or lid.\u003c\/li\u003e\n\u003cli\u003eNi-Slide rod coating supports corrosion resistance for use in saltwater areas.\u003c\/li\u003e\n\u003cli\u003e10 mm rod by 22 mm cylinder sizing gives a clear reference when comparing against the spring being replaced.\u003c\/li\u003e\n\u003cli\u003eGas spring format helps support controlled opening and holding of hatches, lockers, and similar marine access panels.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis Ni-Slide Series gas spring is offered in multiple output force options. The key difference across the range is the pound rating, from lighter 30 lb support up to heavier 180 lb support, while the listed SL29 configuration keeps the same 36.30 inch extended length, 21.10 inch compressed length, 15.20 inch stroke, and 13 mm socket format.\u003c\/p\u003e\u003cp\u003eWhen replacing an existing hatch support, match the output force as closely as possible to the original spring, then confirm the extended length, compressed length, stroke, and socket size against the hardware on the boat. A force rating that is too low may not hold the hatch open properly, while a rating that is too high can make the hatch harder to close or add stress to the mounting points.\u003c\/p\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eBefore installation, measure the current gas spring from socket center to socket center in both the open and closed positions when possible. The mounting brackets should line up without forcing the spring, and the socket ends should seat cleanly on the ball studs.\u003c\/p\u003e\u003cp\u003eGas springs are pressurized components, so they should not be punctured, heated, or modified. If the old spring is oil-filled or damaged, remove and dispose of it with care according to local requirements for pressurized and oil-containing parts.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis range fits boats that need a replacement lift support for hatches, storage lids, access panels, and similar compartments where the SL29 length and socket configuration are already in use. It is most useful for owners, yards, and service techs who want to restore controlled hatch movement without changing the original mounting layout.\u003c\/p\u003e","brand":"Attwood Marine","offers":[{"title":"30 lb","offer_id":52581911101621,"sku":"QBP904531-V1","price":0.0,"currency_code":"USD","in_stock":false},{"title":"40 lb","offer_id":52581911134389,"sku":"QBP904531-V2","price":28.35,"currency_code":"USD","in_stock":true},{"title":"50 lb","offer_id":52581911167157,"sku":"QBP904531-V3","price":0.0,"currency_code":"USD","in_stock":false},{"title":"60 lb","offer_id":52581911199925,"sku":"QBP904531-V4","price":28.35,"currency_code":"USD","in_stock":true},{"title":"70 lb","offer_id":52581911232693,"sku":"QBP904531-V5","price":0.0,"currency_code":"USD","in_stock":false},{"title":"80 lb","offer_id":52581911265461,"sku":"QBP904531-V6","price":0.0,"currency_code":"USD","in_stock":false},{"title":"90 lb","offer_id":52581911298229,"sku":"QBP904531-V7","price":28.35,"currency_code":"USD","in_stock":false},{"title":"100 lb","offer_id":52581911330997,"sku":"QBP904531-V8","price":28.35,"currency_code":"USD","in_stock":true},{"title":"110 lb","offer_id":52581911363765,"sku":"QBP904531-V9","price":0.0,"currency_code":"USD","in_stock":false},{"title":"120 lb","offer_id":52581911396533,"sku":"QBP904531-V10","price":28.35,"currency_code":"USD","in_stock":false},{"title":"130 lb","offer_id":52581911429301,"sku":"QBP904531-V11","price":28.35,"currency_code":"USD","in_stock":false},{"title":"140 lb","offer_id":52581911462069,"sku":"QBP904531-V12","price":0.0,"currency_code":"USD","in_stock":false},{"title":"150 lb","offer_id":52581911494837,"sku":"QBP904531-V13","price":28.35,"currency_code":"USD","in_stock":true},{"title":"170 lb","offer_id":52581911527605,"sku":"QBP904531-V14","price":0.0,"currency_code":"USD","in_stock":false},{"title":"180 lb","offer_id":52581911560373,"sku":"QBP904531-V15","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1333070_qbp904531.jpg?v=1780201482","url":"https:\/\/www.qualityboatparts.com\/products\/qbp904531","provider":"Quality Boat Parts","version":"1.0","type":"link"}
