Using Tylaska's Spool Shackles instead of a bowline knot is easier to do that to describe how to use them to attach a looped end of line to jib, genoa, or asymmetric clew ring. Run the appropriately-sized loop through the open center of the spool and through the clew ring or even use to attach halyards. Insert the retaining pin so that it separates both of the folded parts running through the center of the spool. Double the line back around the spool, peel back the loop around the top and the bottom of the spool, and then snug the ﾓO in ring to the side of the loop and spool. It's a bit like starting the first crochet loop. Sailors have been using them for years on asymmetric spinnaker sheets and they are holding when they need to hold. It is a lot easier to ﾓbreak their backs in and untie them than it is a bowline after they have been under load. The spool shackle works with conventional and high-tech line.
The T4 is made of high-impact polycarbonate and has a breaking strength of 4,400 pounds.
