How do you mend a damaged shutter staple? Locate and clear away the broken 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 existing staple holes on the tilt rod.
