P4 Polycarbonate Spool Shackle, Tylaska Marine And Aerospace, Mfr#: P4

The S-Series Tylaska Spool Shackle is machined from high-strength aluminum. The P4 version of the Tylaska Spool Shackle is made of high-impact polycarbonate. Both versions have an exceptional strength-to-weight ratio. The key is that the line itself supplies the strength while the shackle simply redirects the force. The ease of unfastening after loading is equally amazing. Based upon the concept of “breaking the back” of a bowline knot, the line can be rolled back and taken off even after it becomes “stiff as a wire” from tension.
