An adapter closure structure for electrical conduit systems of the type
having conduit bodies, for which additional conduit access to an
in-service conduit junction box can be provided without the need for
removing and/or rewiring the in-service junction box. In a first
embodiment, a structure is provided in the form of a closure plate having
one or more conduit hubs to replace a flat closure plate on one side of a
conduit body. In a second embodiment, a second conduit body may be joined
to the in-service body utilizing a novel coupling ring. In this
alternative embodiment, the second body can provide additional interior
working space. In addition the second body may also optionally add one or
several additional conduit hubs for added access to the in-service
system. In both embodiments, the closure structure is fitted into a
female opening of the conduit body for structural integrity.
