Ronstan RF254 Transom Gudgeon – 6.4mm Stainless Steel Rudder Fitting

Ensure a strong and reliable rudder connection with the Ronstan RF254 Transom Gudgeon—a durable transom-mounted fitting designed to securely hold your rudder via a pintle system.

This gudgeon forms the fixed receiver component of the rudder assembly, working in conjunction with a compatible pintle (such as the RF255) to provide a smooth, stable pivot point for steering.

Manufactured from marine-grade stainless steel, the RF254 offers excellent corrosion resistance and long-term durability, making it ideal for saltwater environments and demanding sailing conditions.

Designed for 6.4mm (1/4") pintles, this fitting ensures compatibility with standard rudder hardware used across dinghies, catamarans, and small keelboats.

The four-hole mounting base provides a secure and stable installation on the transom, maintaining correct rudder alignment and reducing wear over time.

Compact, strong, and easy to install, the RF254 is a dependable solution for both new builds and replacement rudder systems.
