Tylaska Spool Shackles

Tylaska Spool Shackles

Spool Shackles by Tylaska rid your sheets and halyards of the needless weight of traditional shackles. These patent pending, Tylaska shackles will not jam and remain easy to fasten and unfasten even after loading up to the tensile strength of the line. Machined from high-strength aluminum, the Spool Shackle has 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 Spool Shackle works with both conventional and hi-tech lines. All that's needed is an eye spliced (looped) end. Better yet, you don't have to open a spliced loop and then resplice it to attach the Spool Shackle to a line. Just slide the Spool Shackle on and close the retaining pin. The retaining pin keeps the Spool Shackle captive on the loop when not in use and can be removed for transferring to another line. An "O" ring is included but its use is optional. (Slides down against loop locked end of line for extra security against release during sail flogging. Testing thus far indicates the "O" ring is not necessary.)
