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