How do you mend a cracked shutter staple? First, remove the damaged staple away from the louver with a tool like of needle-nose pliers. Then dab on some adhesive (like wood glue or epoxy) to coat the legs of a new staple. Thread the staple into the loop on the louver and slide its legs into the same staple holes on the tilt rod.
