The frame is made from anodized aluminum, giving it strong resistance to the corrosive effects of saltwater and marine air so it holds up season after season. The lid is fitted with a seal and acrylic pane set into the aluminum frame, creating a leak-proof assembly that is designed for straightforward replacement of an existing flange-style hatch.\u003c\/p\u003e\u003cp\u003eOutside handles let the hatch be opened from the deck when it is not locked, and integrated friction levers hold the lid open in virtually any position up to 95 degrees, so it stays put instead of slamming shut in a breeze. The hatch is finished in grey and is sized as Lewmar Size 70. It ships as a single hatch unit; mounting hardware is not included, so installers should have their own fasteners and sealant on hand. Lewmar backs this flange base hatch with a three-year warranty.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Lewmar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 39970020\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Flange Base Hatch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e Size 70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Grey\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Material:\u003c\/strong\u003e Anodized Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Opening Angle:\u003c\/strong\u003e 95 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Hatch (mounting hardware not included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 31.02 x 24.33 x 4.09 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 33 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Three-year warranty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 743683116186\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Lewmar 39970020 flange hatch?\u003c\/strong\u003e The Lewmar 39970020 flange hatch is Lewmar Size 70, a medium profile design finished in grey.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the frame made of?\u003c\/strong\u003e The frame of the Lewmar Size 70 flange hatch (part 39970020) is anodized aluminum, chosen for its resistance to corrosion in marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow far open can the hatch lid be held?\u003c\/strong\u003e Integrated friction levers on the Lewmar 39970020 hatch let the lid be held open in virtually any position up to 95 degrees.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the hatch be opened from outside the boat?\u003c\/strong\u003e Yes, the Lewmar Size 70 flange hatch has outside handles that allow it to be opened from the deck whenever it is not locked.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Lewmar 39970020 hatch include mounting hardware?\u003c\/strong\u003e No, mounting hardware is not included with the Lewmar Size 70 flange hatch; only the hatch unit itself ships.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this hatch weigh?\u003c\/strong\u003e The Lewmar 39970020 flange hatch weighs 33 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this hatch leak-proof?\u003c\/strong\u003e The lid uses a seal and acrylic pane fitted into the anodized aluminum frame to create a leak-proof assembly on the Lewmar Size 70 flange hatch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Lewmar 39970020 hatch a genuine Lewmar part?\u003c\/strong\u003e Yes, part number 39970020 is a genuine Lewmar Size 70 flange base hatch, not a generic aftermarket copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat warranty comes with this hatch?\u003c\/strong\u003e Lewmar backs the Size 70 flange hatch, part 39970020, with a three-year warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Lewmar 39970020 hatch?\u003c\/strong\u003e This flange hatch is finished in grey.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions of this hatch?\u003c\/strong\u003e The Lewmar Size 70 flange hatch ships in packaging measuring 31.02 x 24.33 x 4.09 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this hatch designed as a replacement part?\u003c\/strong\u003e Yes, the Lewmar 39970020 is a replacement flange base hatch intended to replace an existing Size 70 flange-style hatch on a boat.\u003c\/p\u003e","brand":"Lewmar","offers":[{"title":"Default Title","offer_id":49025133084891,"sku":"LEW-39970020","price":1320.03,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/51IS-cKEwvL_5e10a5ce-b686-4d4f-a6dc-2e4174d9ff0b.jpg?v=1785331089","url":"https:\/\/www.goodvibesmarina.com\/products\/lewmar-size-70-medium-profile-flange-hatch-grey-anodized-aluminum-part-39970020","provider":"Good Vibes Marina","version":"1.0","type":"link"}
