How do you fix a cracked shutter staple? First, clear away the damaged staple away from the louver with some of needle-nose pliers. Then apply some adhesive (like wood glue or epoxy) to spread all over the legs of a replacement staple. weave the staple through the loop on the louver and slide its legs into the same staple holes on the tilt rod.
