These Wide D shackles are made from AISI 316 marine grade stainless. They are high strength and polished to a mirror finish.
SGS Test Report for Proceans Wide D Shackles:
The tensile strength of a material is the maximum amount of tensile stress (pull) that it can take before failure measured in Kilonewtons (kN) or kilograms-force (Kg). BL or Breaking Load is a similar measurement.
8mm wide D shackle - maximum tensile force = 7.21kN or 1,350Kg
10mm wide D shackle - maximum tensile force = 24.5kN or 2,500Kg
12mm wide D shackle - maximum tensile force = 39.2kN or 4,000Kg
PLEASE NOTE: SAFE WORKING LOAD IS RECOMMENDED AT APPROXIMATELY 20% OF MAXIMUM TENSILE FORCE
