Spool Shackles
This revolutionary, patent
pending 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 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.
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.
