Description

Ronstan Series 55 Ratchet Orbit Block™ – Single – Swivel Head – Auto & Manual – Marine Electrical Replacement Part is organized for electrical wiring & connectors shoppers who need a clear, professional marine parts buying experience.

Series 55 Ratchet Orbit Block™ – Single – Swivel Head – Auto & Manual Automatic Ratchet Block Now you can enjoy the flexibility of setting up your ratchet blocks to suit yourself. Ronstan is the only company that offers a ratchet block with both auto and manual engagement modes. 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. In manual mode, the ratchet mechanism can be switched on or off as required. This is the preferred mainsheet set-up for may top sailors. Try the block in both modes and see which you prefer
