The 91618 Roller Spindle is a heavy-duty zinc-plated steel boat trailer roller pin designed to suit compatible 12" flat roller brackets. Measuring 345mm overall length × 22mm diameter, it provides a strong mounting shaft for larger keel and centre roller assemblies. Its zinc-plated finish provides added corrosion resistance, making it a practical replacement for boat trailer spindles that have become bent, heavily worn, grooved or corroded.
