Hammer Head Lumber and Building Supplies has closed. A sign posted on the door announces that the store, located on Highway 19 just south of Zebulon, has ceased business. "Thank you for your support for the past 10 years. It has been a pleasure to serve you and the community," the sign reads. A vacant parking lot fronts the strip mall housing Hammer Head. The strip mall is nearly vacant. Crumb Crazy, a bakery at the other end of the strip mall, is closing Friday, July 31.
