57mm Carbo Ratchamatic Blocks




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
