A reinforcement assembly for a spacer fitting for a utility pole comprising a front plate and back plate assembly having a connection aperture located at a top portion of both the front and back plates. The connection apertures may be configured to have substantially the same diameter as an insulator aperture located on the spacer fitting. The connection apertures provide an attachment area for the reinforcement assembly to be attached to the spacer fitting. The reinforcement assembly may be attached to the spacer fitting at an insulator aperture for supporting a strand of insulators and/or transmission lines. The front and back plates also may each include a receiving aperture located at a bottom portion of both plates. The receiving apertures may be used to support insulators and/or transmission wires on a transmission or utility support structure.
