Description
Description
The Ronstan Series 55 Orbit Ratchet Block with Link Head is a high-performance single ratchet block for dinghy sailors who want more grip, faster easing and better sheet control.
Its 55 mm aluminium sheave delivers serious holding power, while the Dyneema® Link Head keeps the attachment light, secure and clean. Ideal for dinghy mainsheets, spinnaker sheets and other high-load control line applications.
Auto and manual ratchet in one block
The big USP: Ronstan offers a ratchet block with both automatic and manual engagement modes.
In auto mode, the ratchet engages when load is applied and switches off when the load is released. This gives you holding power when the pressure is on, while the sheet still runs out smoothly when you ease.
In manual mode, you decide when the ratchet is switched on or off. Many top sailors prefer this setup for mainsheet control because it gives a direct and predictable feel.
