  • Structural Integrity: Each block is engineered with a Minimum Ultimate Strength equal to four times the Working Load Limit (4 X WLL).
  • Standard Secure Fastening: Blocks are fitted with a 319AN style swivel hook that includes a safety latch and split pin to prevent accidental load release.
  • Certified Quality: Third-party testing and official certification are available upon request to meet specific project safety standards.
  • Integrated Becket: Every unit is standard-fitted with a becket suitable for connecting an Open Wedge Socket matched to the indicated wire rope diameter.
Technical Versatility and Design

  • High-Visibility Finish: Standard units are painted in a high-visibility yellow (without striping) for easy identification in the field.
  • Operational Flexibility: While primarily a single sheave design, these blocks are versatile enough to be utilized with 2 lines when necessary.
