RWO 57mm Macro Ratchet Block Fiddle & Swivel

Ratchet Blocks have great gripping power under load, whilst still allowing the rope to be released freely when required. They are ideal for allowing the crew to hand hold main, jib and spinnaker sheets and ease sail safely. Featuring specially designed sheaves made of carbon filled nylon combining high strength and corrosion resistance. The sheaves run on twin races of precision ground Delrin ball bearings for minimum friction under high or low loads. The sheave groove profile only grips a 10mm rope when under high loads. A 'Planar' switch system is used to allow easily operated on/off selection of ratchet mechanism with cold. wet or gloved hands, even under load. The series includes a reverse action / rotation single block which when paired with a standard model always has the switch facing the crew, ideal for jibs and spinnaker sheets. Standard models, single, (and Becket), and fiddle are all available with adjustable cam cleat arms.
