A guide wire assembly for the support of electrical cabling that extends from an electrical source point, such as an electrical pole, to a use location. The guide wire assembly includes a housing having a base end, an extended end and a longitudinal passage extending between the base end and extended end; an insert constructed and arranged for positioning within the longitudinal passage and having a center bore; a threaded rod having proximal and distal rod ends, the distal end of the threaded rod mating with the center bore of the insert; a coil spring disposed within the longitudinal passage of the housing and about the insert; a first attachment mechanism supported at the proximal end of the threaded rod and for support of a guide wire; and a second attachment mechanism supported at the base end of the housing.
