  • Lightweight and durable construction
  • Articulating Fork Head with threaded pin for secure attachment and improved alignment under changing load angles
  • Block can articulate on the attachment fitting for enhanced rope alignment and reduced side loading
  • Patented Dynamic Bearing System featuring twin rows of stainless-steel ball bearings running on a stainless-steel rail for superior load capacity and longevity
  • Integrated Becket with a large central rivet, providing a lightweight and rope-friendly attachment point for cascade systems
  • Ideal for applications requiring smooth, efficient line handling and flexible attachment positioning
  • Suitable for use with smaller diameter rope lines in a wide range of marine and control line systems
