Description

  • 【Advanced ball bearing system】 Engineered with high strength delrin ball bearings to provide ultra low friction under dynamic loads. It ensures smooth rope release and trimming without jamming, turning sliding friction into rolling efficiency.
  • 【Marine grade materials】 Constructed with a 316L stainless steel load bearing axis and shackle for ultimate saltwater corrosion resistance. The sideplates use UV stabilized pa66 nylon with fiberglass, balancing extreme strength with a lightweight design.
  • 【Lockable swivel head and becket】 The top shackle freely rotates 360 degrees to prevent line twisting, or can be locked at 0 or 90 degrees via an integrated set screw. The bottom becket pin serves as a secure anchor for block and tackle setups.
  • 【High working load limit】 Built for extreme reliability. This 50mm sheave accepts rope sizes up to 10mm, featuring a safe working load of 450kg or 1000 lbs and an impressive breaking strength of 1000kg or 2200 lbs.
  • 【Versatile application scenarios】 Perfectly designed for marine mainsheets, halyard tuning, and spinnaker systems. Beyond boating use, it is ideal for heavy duty outdoor canopy tensioning, arborist rescue hauling, and industrial hoisting.
