Carbo Pulley 57 mm Ratchamatic Flip-flop RONSTAN
Designed to pivot around the rope's axis, it keeps the halyard as close to the deck as possible and adapts to multiple orientations thanks to its articulated system.
It allows free movement in both directions under low loads, then automatically engages a ratchet mechanism when tension increases; this offers precise control and an exceptional power ratio of up to 15:1.
