A one-piece hammer strap is disclosed for attaching ductwork to the superstructure of a building. The hammer strap comprises a baseplate, a strap and a fastening device. The strap is attached at one end to the baseplate, threaded around the ductwork and through a slot in the baseplate. The strap can be bent at the slot to firmly grasp the ductwork. The hammer strap can be attached to the superstructure prior to the installation of the ductwork, using the fastening device. The one-piece hammer straps, and the method of using such hammer straps to install ductwork, allow a single installer to install the ductwork without the need for an assistant.
