How do you repair a broken shutter staple? To start, pull out the snapped staple from the louver with a pair of needle-nose pliers. Then dab on some adhesive (like wood glue or epoxy) to cover the legs of a new staple. guide the staple through 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 513-216-9740.
