How do you fix a cracked shutter staple? First, pull out the snapped staple out of the louver with some of needle-nose pliers. Then use some adhesive (like wood glue or epoxy) to cover the legs of a new staple. weave the staple through the loop on the louver and guide its legs into the previous staple holes on the tilt rod.
