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 aluminium. The P4 version of the Tylaska Spool Shackle is made from 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 un-fastening after loading is eaqually 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 high-tech lines. All that is needed is a looped end. This can be 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 transfered to other lines. An optional "O" ring slides over the line to provide a secondary 'lock' against loosening during the most severe flogging situations.
