Metal Collar for Windsurfing Extension
Specifically made for the Nautix mast extension to fit SDM masts.
It has a 45.5mm inside diameter/47.7mm outside diameter - will work with many mast extensions with an O.D. of approx 45mm and grooved location system, but will need to be used with this Nautix Plastic Ring Collar, which firmly locates inside the metal collar. https://24-7boardsports.com/nautix-plastic-ring-windsurfing-collar/
