ABSTRACT:
This disclosure relates to a closure hatch assembly for the access port of a utility pole of the type particularly suited for supporting an electrical device and housing the electrical cables required to provide power to the electrical device. The closure hatch assembly has a hatch plate made of a composite, non-conductive material and is of such dimensions as to close the access port. A lip extends outwardly from the periphery of the closure plate to engage the exterior surface of the utility pole circumjacent the access port. A groove, or channel, is provided on the hatch plate to receive a hollow bracket member. The hollow bracket member is also made of a non-conductive composite material. When received within the channel, the bracket member has sufficient length to extend beyond the hatch plate to engage the interior surface of the utility pole. The bracket member may be secured to the hatch plate and maintained in abutment with the interior surface of the utility pole by a metal fastener which is threaded into a sheet metal nut that is supported from the bracket member. The bracket member is configured such, and is embraced by the channel such, that no wires can engage the threaded metallic screw or the sheet metal nut.
