2x D-loop lengths, tie your d-loop at home!

You should replace your string D-loop when it starts to have visible signs of wear, this includes outer material falling apart, melted ends beginning to crack from pressure, and if you can see any white inner material at all do not use your bow until the d-loop is replaced.

Both D-loop lengths included will be at least 6 Inch, allowing you to easily tie a new loop on to your string as pictured, with material to spare. Check out an online tutorial on how to tie a D-loop.
