Harken 57mm Triple Carbo Ratchet Block with Cam & Becket (2141)
High-purchase sail control with dependable holding power and integrated cleating
The Harken 57mm Triple Carbo Ratchet Block with Cam & Becket (2141) is designed to give sailors maximum mechanical advantage and hands-on control in compact, efficient systems. With three sheaves, an integrated Cam-Matic® cleat, and a becket for tie-off, it’s ideal for multi-part mainsheet and control line systems on performance dinghies and small keelboats.
The Carbo Ratchet mechanism provides a reliable balance of holding power and smooth, controlled easing, allowing sailors to confidently hand-hold loaded lines while trimming or bearing away. Built from lightweight, fibre-reinforced composite materials, it reduces weight aloft without compromising strength or durability.
Perfect for systems where active, high-frequency adjustments are key, the 2141 delivers responsive performance and efficient line handling across a wide range of wind conditions.
