Tylaska’s line of SS plunger pin style shackles were developed based on the original tried-and-true Sparcraft SS20 design. Through rigorous testing and optimization, Tylaska has improved upon the original design to increase the reliability, functionality, and fatigue life of the shackles. In addition to the optimized SS20L, Tylaska also offers two scaled versions of the shackle; the smaller SS10 and the larger SS40L. The SS20L and SS40L are fully traceable and bare the CE mark denoting their approval for use as lifting accessories. The SS10 is intended for static load applications only and is not approved for lifting applications.
