Harken 57mm Carbo Fiddle Ratchet Block
Lightweight control with powerful holding force
The Harken 57mm Carbo Fiddle Ratchet Block is designed for responsive sail handling in small keelboats and performance dinghies. Combining a high-strength fiddle block layout with an integrated ratchet, it offers excellent mechanical advantage and grip for mainsheet systems under load.
Constructed from Harken’s lightweight, fibre-reinforced Carbo composite, it delivers reliable performance with minimal weight aloft. The ratchet mechanism can be switched on or off for precise control, while the fiddle configuration makes it ideal for cascaded purchase systems where space and weight are at a premium.
