Windesign Low Friction Rings: Make your own 4:1 mainsheet block-ring combination
The Wingdesign 38mm ring is mainly intended to create a 4:1 mainsheet system. Similar to our existing block combination, the EX1319, you can replace the 29mm Harken block by the 38mm Windesign ring. By changing this block, you create a low friction, less heavy and more durable block combination.
