    602330 Ronstan Ronstan Series 55 Ratchet Orbit Block (RF56530) RF56530

    The world's best ratchet block is now even better. The Ronstan Series 55 Ratchet Orbit Fiddle Block with a Cam Cleat and Becket (RF56530) boasts the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and a Dyneema® rope link head. Their precision design allows the optimum number of ball bearings in loaded areas and eliminates them in inactive areas. Ineffective mass is reduced even further through fiber-reinforced composites in the block head, cleat arms and beckets.

    • Ultra Lightweight
    • Low friction 2-stage Orbital ball bearing system
    • Highest working load in its class
    • Up to 20:1 holding power
    • Low profile and compact
    • High performance cleating

    • Mainsheet systems on dinghies, sportsboats and small keelboats to 9m (30ft)
    • Spinnaker sheets on dinghies, sportsboats and small keel boats to 9m (30ft)
    • Halyard, Vang and Backstay application on boats to 8m (26ft)
    • Control line applications on larger yachts

    Specifications:

    • Sheave: 2-5/32" + 1-3/8"
    • Max. Line Size: 3/8"
    • Max Working Load: 550 lbs.
    • Breaking Load: 1650 lbs.
