Sea-Dog Stainless Deck Fill Key 351399-1 — Product description

This Sea-Dog deck fill key is the little stainless tool that saves you from fighting a stuck fill cap at the dock. Cast stainless steel, built to fit any deck fill with holes spaced 1-3/16 inches on center. Drop it in the two holes, give it a turn, and your fuel or water cap backs right out.

If you've ever stood on a rocking deck trying to twist open a keyed fill cap with cold fingers, you already know why this tool exists. The Sea-Dog deck fill key seats into the two recessed holes on top of your deck fill, giving you the grip to back the cap out clean and snug it back down when you're done fueling or taking on water.

It's cast from stainless steel, so it shrugs off salt spray and lives happily in a cockpit locker or glovebox for years. The pins are spaced 1-3/16 inches on center, which matches the standard keyed fill caps you'll find on most boats. That's the measurement that matters. If your cap's holes line up at 1-3/16 inches, this key fits. It's sold as a single key, so grab one for the boat and maybe a spare for the dock box. Small, cheap, and exactly the kind of thing you're glad you have the day your cap won't budge.

Frequently asked questions

What size fill caps does this key fit?

It fits any deck fill cap with two holes spaced 1-3/16 inches on center, which is the common keyed-cap pattern on most boats. Measure the center-to-center distance between the two holes on your cap to confirm the fit.

What's it made of?

Cast stainless steel, so it holds up to salt spray and won't rust sitting in a damp cockpit locker or dock box.

Do I get one key or a set?

This is sold as a single key.

What is a deck fill key used for?

Keyed deck fill caps, the ones for fuel, water, or waste, have two small holes on top instead of a wing or lever. This tool drops into those holes so you can twist the cap open and closed without scratching it up or fighting it by hand.
