FMR Rings are used for hauls, sheet rings or for the construction of 3d tack points. The inner radius is designed for minimum friction with small to medium deflection. All rings come with our "Low Friction" surface for highest gloss and minimum friction. A silicon ring protects deck and deck house. Rings are in stock from 23 mm opening for dinghies and smaller kell boats up to 42 mm for bigger yachts. More sizes as custom parts as well are available.
