How do you mend a cracked shutter staple? Locate and pull out the snapped staple out of the louver with a pair of needle-nose pliers. Then use some adhesive (like wood glue or epoxy) to cover the legs of a replacement staple. weave the staple through the loop on the louver and direct its legs into the same staple holes on the tilt rod. For replacement shutter staples, call us at 208-609-9129.
