A suspension or staying system (20) uses a length of wire or cable (21) with a hook (22) or plain bead secured to one end. The hook (22) may be secured directly or indirectly to a structure, or pass around a fixed structure such as a beam, purlin or girder, or something fixed thereto, such as a clip, hook or eye, and hooked to the length of wire to form a loop. The hook (22) may include an enlarged beaded end which may be used directly with some fasteners or clamps, or with a clip to form a loop. The clip may be used with the plain beaded end or a hooked beaded end (22). The enlarged bead of either enables the length of wire to be caught by somewhat smaller holes in a variety of structural fasteners. The other or free end of the wire or cable (21) is extended through a jam cleat (27) and around an object to be suspended or stayed, and then back through the jam cleat (27) to form a tightenable, adjustable loop simply by pulling on the free end. The jam cleat (27) uses swinging wire gripping levers accommodating a range of wire sizes driving the wire against a curved surface tightly to grip the wire to prevent wire movement in one direction. In one form the jam cleat may be locked for seismic applications. Also included is a cleat or termination for directly or indirectly supporting or hanging a fixture or object without passing the wire or cable around the object. <IMAGE> |
