  • Patent number: 5433333
    Abstract: This disclosure relates to a closure hatch assembly for the access port of a utility pole. The access port has opposed, lateral edges and opposed, longitudinal edges. The hatch plate has a closure wall that is adapted to close the access port. The closure wall has a reverse face with laterally spaced protuberances extending outwardly therefrom. Opposed walls on the protuberances define a channel therebetween, and a bracket member is receivable within the channel. The bracket member presents longitudinally spaced bearing surfaces that are adapted operatively to engage the opposed longitudinal edges of the access port. The bracket member also has laterally spaced walls that are receivable within the channel in sufficiently close proximity with the opposed walls that define the channel in order to transfer compressive forces therebetween. A fastener releasably secures the bracket member within the channel and thereby mount the bracket assembly to the utility pole.
