Abstract
The present disclosure relates to a method of installing a spacer fitting repair device on a utility support structure. The method includes removing an insulator strand from an insulator aperture of a spacer fitting, abrading a first outer surface and a second outer surface of the spacer fitting connected to the utility support structure to create roughen the first and second outer surfaces, positioning a front plate against a portion of the first outer surface, positioning a back plate against a portion of the second outer surface, and clamping the front plate and the back plate to the spacer fitting. The method may be used to repair spacer fittings for supporting utility transmission wires or cables.
