ABSTRACT:
Improved metallic utility pole accessories used to either support objects on a utility pole or to support and stabilize the pole are provided. In general, the utility pole accessories include a polymeric chemically bonded coating that protects the underlying metal surface from corrosion. The coating also is substantially dielectric for preventing the accessories from interfering with the transmission of electricity through lines supported on the poles. The polymeric coating can be made from polymeric materials having functional monomers grafted thereto for chemically bonding with metal surfaces. Specific accessories within the scope of the present invention include crossbars, anchoring pins, transformer boxes, and guidewire supports. Also included is an improved insulator support post having a threaded portion made from a structural plastic material bonded to the polymeric coating.
