Sea-Dog Adjustable Bronze Deck Plate Key – 6" Max Opening
A heavy-duty, adjustable deck plate key built from sand cast bronze — the most durable material available for this type of tool. Unlike fixed-pin keys, this one adjusts to fit a wide range of deck plates and strainer caps, and comes with two interchangeable stainless steel pin sizes to handle virtually any standard fitting on your boat.
Key Features
- Adjustable span opens to a maximum of 6" — fits most standard deck plates and caps
- Includes two stainless steel pin sizes: 3/16" and 5/16" for broad compatibility
- Sand cast bronze construction for exceptional strength and corrosion resistance
- Drilled handle allows attachment of an optional lanyard to prevent loss overboard
- A reliable, long-lasting addition to any onboard toolkit
Parts Desk Insights
Best use case: This is the right key when you have multiple deck plates of different sizes or styles on your boat and want one tool that handles all of them. The adjustable span and dual pin sizes make it compatible with virtually every standard screw-out deck plate and strainer cap. It’s also the preferred choice for professional use or any situation where a plastic key isn’t durable enough. For a fixed bronze spanner wrench, see the Groco SW-2531 Bronze Spanner Wrench. For lighter-duty or occasional use, see the Universal Deck Plate Key or the Deck Plate Key. To keep this key tethered, pair it with the Sea-Dog Deck Plate Lid Lanyard.
