Optiparts mast lock for Optimist EX1203

The pin type maststep must be used together with the pin type heel plug. Friction between mast and maststep is reduced to a minimum. Most popular is our round type maststep. This maststep has an oval cup, which allows the mast to tilt forward when going downwind. Different mast rakes can easily be repeated using the scale on the base. New for 2007: Mast step locking system. Stainless steel spring which prevents the nut from turning accidentally. There is no need for additional locking nuts anymore.
