Each shackle has a Product Identification Code (PIC) for material
traceability along with a Working Load Limit and the name Crosby forged into
it.
Increased radius of bow gives wider sling bearing surface
resulting in an increased area for load distribution, thus:
Increasing Synthetic Sling efficiency as compared
to standard anchor and chain shackle bows and
conventional eye hooks. This allows 100% of the
slings rated Working Load Limit to be achieved.
Allowing better load distribution on internal fibers.
Crosby products meet or exceed all the requirements of
ASME B30.26 including identification, ductility, design factor, proof load and
temperature requirements. Importantly, Crosby products meet other
critical performance requirements inluding fatigue life, impact properties and
material traceability, not addressed by ASME B30.26.
Shackles available in both a Scre Pin and Bolt, Nut and cotter pin
configuration.
Bolt (Pin) has a larger diameter that provides better load
distribution.
Look for the Red Pin ... The mark of Genuine Crosby Quality
