Can I use the wire guardian as the hook for my clasp?
We wouldn't recommend using the Accu-Guard™ wire protector as a hook, but it could be used as the loop or "eye" side of a "hook-and-eye" clasp configuration. Most of the Accu-Guard wire protectors have the outer diameter of approximately 4mm. If the hook portion of the clasp is small, it should go through the Accu-Guard. Adding a soldered jumpring to the end of your strung design would eliminate any doubt and provide a very secure end to your design.
