Now you can enjoy the flexibility of setting up your ratchet blocks to suit yourself with the Ronstan RF56100 Series 55 RT Orbit Block Single Swivel Head. In the auto mode of the ratchet mechanism engages when load is applied, but switches off when it's released. This lets the sheet run out smoothly and freely-great for rapid easing of the sheet and for gybing asymmetric spinnakers.

Ronstan RF56100 Series 55 RT Orbit Block Single Swivel Head Features:
  • Automatic ratchet block
  • Awesome ratchet block holding power
  • The sophisticated NC-machined sheave features Generation 2 of our patented sheave cross-hole geometry. Its holding power is up to 21:1
  • The unique sheave design has 12 gripping faces which directly resist loaded line movement
  • Generation 2 design has straight resistance faces which both distribute the load and minimise rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load
  • Smooth easing of sheets
  • High performance cleating
  • Swivel shackle head for unlimited block rotation
  • Stainless steel shackle head for ultimate durability and compatibility with harsh fixing points
  • Applications:
    • Mainsheet systems and spinnaker sheets on dinghies, sportsboats and small keel
    • boats to 8m(26ft).
    • Halyard, vang and backstay applications on boats to 8m (26ft).
    • Spinnaker sheets on sportsboats and small keel boats (lateral lead blocks)
