Description



Control loaded lines with ease

The 57mm and 75mm Carbo Ratchamatic blocks are adjustable for use in many applications and weather conditions. This load-sensing ratchet block rolls freely in both directions under low loads, then engages the ratchet automatically as loads increase. With 180 degree wrap, you get a 10:1 holding power. Great for asymmetrical spinnakers when you need tough holding power and a quick release.

  • Sheave: Hardkote anodized eight-sided aluminum
  • Sheave Size: 1-9/16" (40mm)
  • Ball Bearings: Engineered plastic in fitted ball races
  • Line Diameter: 3/8"
  • Cheek Material/Finish: Long-glass reinforced engineered nylon
  • Shackle/Strap Type: Stainless swivel shackle

    Comments about 75mm Carbo Ratchamatic Blocks:

    We use these blocks to help get the genoa in on a 24ft racing yacht. The blocks work well and help to the extent that most of the time, winching in the sail is no longer needed. This means faster, crisp tacks. We have not yet decided upon the best setting at which the ratchet engages, but a few more races and we will find a good all round setting.
