How do you mend a broken shutter staple? First, remove the snapped staple away from the louver with a tool like of needle-nose pliers. Then use some adhesive (like wood glue or epoxy) to spread all over the legs of a new staple. Thread the staple through the loop on the louver and guide its legs into the existing staple holes on the tilt rod. For new shutter staples, call us at 847-250-6544.
