Heavy duty round boat cleat is 4-hole open-base Herreshoff deck cleat, which is a staple choice for heavy-duty mooring and docking applications. It features a mirror-polished finish and a hollow, open center that allows lines to be easily looped or tied off. These hardware components are primarily crafted from marine-grade 316 stainless steel, which offers superior resistance to rust, saltwater, and extreme weather.
Key Features of this Cleat
Material Construction: Typically forged or investment-cast from marine-grade 316 stainless steel to ensure maximum resistance to corrosion and rust in harsh saltwater environments.
Mounting Base: Built with a four-hole configuration split across two separate rounded footings.
This geometry distributes structural stress more evenly across the boat deck or dock surface compared to standard two-hole designs.
Hollow Open Base: The open architecture provides ample clearance under the main crossbar, making it much faster to pass dock lines through during tight docking maneuvers.

What overall length (e.g., 6-inch, 8-inch, 10-inch) do you need for your boat's line thickness?
