Selden Automatic Ratchet Block - 45mm
For dinghy and keelboat main sheets and spinnaker sheets. Makes it easy to advance your grip when hauling in the sheet. The perfect combination of control and convenience.
- Ø5 mm Delrin ball bearings and Ø45 mm aluminium sheave.
The sheave automatically changes from free-turning to ratchet when the load increases. The sailor decides when the automatic ratchet kicks in. The switch-over point is set using an allen key to adjust a screw inside the sheave. Fast, simple, precise.
The shackle can be locked in-line with the sheave or at 90º. It can also be set to swivel freely.
