The Ronstan RF144 Steering Pulley (Swivel Shackle Head) is a compact, heavy-duty pulley designed for mechanical steering systems on small boats, runabouts, and yachts. Built for both wire cable and rope steering setups, it ensures smooth, low-friction operation and reliable steering control.

Featuring a 65mm acetal sheave with a deep groove, the RF144 securely cradles steering wire up to 5mm diameter, reducing wear and ensuring efficient movement under load.

The swivel shackle head allows flexible alignment with steering runs, making installation easier and improving system efficiency—especially in tight or complex steering layouts.
