It is machined from investment cast 316 stainless steel, giving it strong resistance to the saltwater, fuel, and weather exposure that deck hardware faces on a daily basis. The key engages the slotted openings on compatible deck fill caps, which are used to access fuel, water, and waste fill points on a boat.\u003c\/p\u003e\u003cp\u003eThis key is sized to fit Sea-Dog cast stainless steel deck fill caps with holes on 1-3\/16 inch centers, specifically the 351320-351331 and 351350-351353 series. Keeping a dedicated key on board (or a spare in the tool locker) makes it easy to open a fill cap when the built-in key feature on some caps is worn, missing, or hard to grip with wet hands. Because it is a separate accessory rather than part of the cap assembly, it can be replaced on its own without buying a new fill cap.\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 351399-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Deck Fill Key\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Investment Cast 316 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 1-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.054 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514351034\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits Sea-Dog cast stainless steel deck fill caps 351320-351331 and 351350-351353\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eFits Sea-Dog cast stainless steel deck fill caps with 1-3\/16 inch hole centers, series 351320-351331 and 351350-351353\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sea-Dog 351399-1 deck fill key used for?\u003c\/strong\u003e It opens and closes Sea-Dog cast stainless steel deck fill caps by engaging the slotted opening on the cap, giving you a dedicated tool for accessing fuel, water, or waste fill points on a boat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich deck fill caps does the 351399-1 key fit?\u003c\/strong\u003e This key fits Sea-Dog cast stainless steel deck fill caps with 1-3\/16 inch hole centers, covering the 351320-351331 and 351350-351353 series.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the deck fill key made from?\u003c\/strong\u003e The 351399-1 key is machined from investment cast 316 stainless steel, chosen for its resistance to corrosion in marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long is the deck fill key?\u003c\/strong\u003e The Sea-Dog 351399-1 measures 1-3\/16 inches in length.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the deck fill key weigh?\u003c\/strong\u003e It weighs 0.054 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this key come with a fill cap?\u003c\/strong\u003e No, the 351399-1 is sold as a standalone key.
