Product Description

Ronstan Series 55 Ratchet Orbit Block

Enjoy the flexibility of setting up your ratchet blocks to suit yourself. This ratchet block offers both auto and manual engagement modes. In the auto mode 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. In manual mode, the ratchet mechanism can be switched on or off as required. This is the preferred mainsheet set-up for many top sailors. Try the block in both modes and see which you prefer - you really can't go wrong.

  • Integrated becket; no loose parts
  • Sheave: Hard anodised Aluminium
