We know what youre thinking how can a dog bone be used on a sailboat? Were not playing fetch!.

Well, the type of dog bone were talking about here is not something you would want to feed to your favourite four legged friend.

No, the type of dog bone we are talking about is a small, lightweight, dog bone shaped piece of aluminium. And they are becoming increasingly more popular on modern sailboats.

But how do you use them and why would you want to?

All of our Tii-on blocks are available with a Tii-shackle a loop of Dyneema which is through spliced at one end and diamond knotted at the other.

However, its important that you pair the Tii-shackle and Tii-on block correctly. Otherwise, the block could fail.

It can sometimes be a bit fiddly to get the Tii-shackle around and through the holes of a Tii-on block, so we recommend using a piece of kite line or whipping twine to help pull it through.

Check out this video for a demonstration of how to use a Tii-shackle, Tii-on block and Pad-Tii.
