Ronstan 40mm Orbit Ratchet Blocks deliver up to 14:1 holding power. The manual ratchet can be engaged or disengaged as needed, making it a popular choice for mainsheet systems among top sailors. A swivel shackle head allows unrestricted block rotation and suits sharp mounting points.

Suitable for dinghy mainsheets, fine-tune systems on sportsboats and small keelboats, and systems using the RF7 mainsheet swivel cleat unit. Also suited to spinnaker and jib sheets on dinghies, particularly modern asymmetric classes, as well as control lines on larger yachts.
