CLGR® High Tensile Shackles Bow Type Square Head Pin Blue Pin for Trawling, also called Blue Pin Square Head Bow Shackle, and some customers also call it as Trawl shackle bow type.


Certified to US Federal Specification RR-C-271 Grade A, this high tensile bow shackle is engineered for demanding marine and trawling applications.
