• Transparency in sourcing: Direct-from-supplier shipping with a clearly identified product number for traceability.

Safety, compatibility, and maintenance

To ensure optimal and safe operation, observe these guidelines:

• Only use with 20mm G80 lift chain assemblies that are EN1677 compatible.
• Do not exceed the 15T rated working load limit; verify the lifting setup and balance before each lift.
• Inspect for signs of wear, deformation, or corrosion before use; replace if any anomaly is found.
• Ensure proper pin retention and secure connections during rigging operations.
• Store in a dry environment and clean after exposure to moisture or chemicals to maintain performance.
