This Harken Carbo Ratchamatic 57 mm triple block with becket is an advanced ratchet block for sailing, where efficient line control and low friction are essential.
The block features an automatic load-sensing ratchet function, which allows free-spinning at low loads and engages the ratchet function under higher loads.
The adjustable load sensor allows you to customize the engagement to your needs, while the hard-coat anodized and Teflon-impregnated sheave contributes to high holding power and reliable performance.
