How do you mend a broken shutter staple? To start, clear away the snapped staple away from the louver with a pair of needle-nose pliers. Then dab on 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 slide its legs into the previous staple holes on the tilt rod. For new shutter staples, call us at 808-797-2004.
