Selden 45mm Auto Ratchet Block

Applications:

Dinghy main sheets and Dinghy spinnaker sheets.

Technical Features

Ø5 mm Delrin ball bearings and Ø45 mm carbon fibre reinforced polyetherimide 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. Automatic Ratchet Block Inside: 1) When the block is low-loaded the ratchet mechanism is disengaged and the sheave spins free. 2) When the load on the block increases the ratchet engages and the sheave is locked in one direction.
