Spool Shackles


This revolutionary new shackle from Tylaska replaces the age-old knot! Unlike a conventional knot, the Tylaska Spool Shackle™ will not jam up and remains easy to fasten and unfasten even after loading up to the tensile strength of the line.

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 have exceptional strength-to-weight ratio. The key is that the line itself supplies the strength while the shackle 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.

The Tylaska Spool Shackle™ works with both conventional and hi-tech lines. All that is needed is a looped end. This can be a pre-spliced loop, yet-to-be spliced loop, or simply an overhand knot loop. A retaining pin allows for the shackle to be removed or transferred to other lines. An optional "O" ring slides over the line to provide a secondary "lock" against loosening during the most severe flogging situations.

1. Begin with a loop tied or spliced 2. Push loop into slot in
Spool Shackle
3. Pull loop through Spool Shackle 4. (Optional) Insert keeper pin. This secures Spool Shackle to line
5. Wrap loop against object 6. Pass Spool Shackle through the loop 7. Secure line behind ears od Spool Shackle & cinch tight against object 8. (Optional) Slide "O" ring against loop as a secondary "lock" in situations of severe flogging
1. Slide "O" ring away from loop. BEend slack line backward around spool diameter 2. Roll loop back over slack line (Similar to "breaking the back" of a bowline knot) 3. Turn spool and pass back through loop. 4. Line is now free from objct.
