  1. Jerry Cahill asks 24 Jul 2015

    When the ratchet is on I presume it locks with tension from the sheet, and when off simply acts as a normal block. Is this correct?

      Hi Jerry
      What you are referring to would be an autoratchet which engages under load (the load setting can be adjusted on some blocks). The Organic block is a manual ratchet which has to be switched off if wanting it to run freely.
      When engaged the ratchet block will only spin in the direction you pull in, the sheave (wheel part) of a ratchet block is shaped to grip the sheet a little. to ease the rope out the sheet slides over the locked sheave and with the added friction it makes it easier to hold loads
      I hope that helps
