ABSTRACT:
A frangible guy attachment adapted to be connected between a cable guy and a stationary guy anchor includes first and second elongated coaxial rods. The rods can either be formed as separate elements or can be formed integrally. In both cases the rods are constructed of an elongated rigid structural material. An intermediate coupler is coaxially fixed between the rods. The rigidity of the coupler exceeds that of the rods to concentrate shock bending stresses at an axial transition between one rod and the more rigid coupler. This stress concentration will cause the rod to fracture and break as a result of the sudden impact. A special clevis interconnects the lower end of the lower elongated rod and a conventional guy anchor, preventing subsequent attachment of additional cable guys to the anchor.
