Sea-Dog Deck Fill Key 351399-1, 316 Stainless Steel, Fits 351320-351331 and 351350-351353 Deck Fill Caps

The Sea-Dog Deck Fill Key (351399-1) is a 1-3/16 inch stainless steel key designed to open and close Sea-Dog cast stainless steel deck fill caps. 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.

This 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.
