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.

A method of installing a spacer fitting repair device on a utility support structure comprising:
- 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 roughen the first and second outer surfaces;
- positioning a front plate against a roughened portion of the first outer surface;
- positioning a back plate against a roughened portion of the second outer surface;
- and
- clamping the front plate and the back plate to the spacer fitting.
A method of reinforcing a spacer fitting for a utility support structure comprising:
- grinding the spacer fitting surrounding an insulator connection aperture located on the spacer fitting;
- positioning a front plate comprising a front fastening aperture located on a top portion of the front plate and a front receiving aperture located on a bottom portion of the front plate on the spacer fitting such that the front fastening aperture is substantially lined up with the insulator connection aperture, creating a first passageway;
- positioning a back plate comprising a back fastening aperture located on a top portion of the back plate and a back receiving aperture located on a bottom portion of the back plate on the spacer fitting such that the back fastening aperture is substantially lined up with the insulator connection aperture;
- aligning the front fastening aperture, the back fastening aperture and the insulator connection aperture, creating a first passageway between the front plate and the back plate;
- connecting the back plate, front plate, and spacer fitting together via a fastener;
- and
- clamping the back plate and the front plate to frictionally engage the spacer fitting such that the frictional engagement between the front plate and the back plate on the spacer fitting is sufficient to support a weight of an insulator.

- aligning the front fastening aperture, the back fastening aperture and the insulator connection aperture, creating a first passageway between the front plate and the back plate;
- aligning the front receiving aperture and the back receiving aperture to define a second passageway;
- fastening the back plate, front plate, and spacer fitting together via a fastener;
- and
- installing an insulator to hang from the second passageway.
