How do you fix a cracked shutter staple? To start, pull out the damaged staple from the louver with a pair of needle-nose pliers. Then use some adhesive (like wood glue or epoxy) to coat the legs of a new staple. weave the staple into the loop on the louver and direct its legs into the same staple holes on the tilt rod. For new shutter staples, call us at 615-236-8530.
