This Page Is Currently Under Construction

Master Windrider series blocks are ultra lightweight, high working load, and low friction. The high strength sideplates are stiff glass fiber/ polyamide to provide top performance of working load. The excellent weather-ability protects blocks from breaking down for any sailing condition. Master Blocks are beautiful in design, but simple in use.
