Perko Adjustable Deck Plate Key – Chrome, Fits Up to 8"
A heavy-duty adjustable deck plate key with a polished chrome finish and hardened steel pins. Built to handle larger deck plates and strainer caps up to 8" in diameter — a wider range than most standard keys — making it a versatile tool for boats with larger access ports or a mix of plate sizes.
Key Features
- Adjustable span fits deck plates and caps up to 8" in diameter
- Chrome-plated zinc body with a polished finish — corrosion-resistant and built to last
- Hardened steel pins for reliable grip and long-term durability
- Wider maximum opening than most standard deck plate keys
- A dependable addition to any onboard or dockside toolkit
Parts Desk Insights
Best use case: This is the right key when you have larger deck plates — 6", 7", or 8" — or a mix of sizes across your boat and want one adjustable tool that covers all of them. The 8" maximum span gives it a meaningful reach advantage over the Sea-Dog Adjustable Bronze Key (6" max) and makes it the better choice for larger vessels or commercial applications. For lighter-duty or occasional use, see the Universal Deck Plate Key or the Deck Plate Key. For a fixed bronze spanner wrench, see the Groco SW-2531 Bronze Spanner Wrench.
