  • Patent number: 12170438
    Abstract: A conduit body includes a sidewall defining an internal chamber and at least two ports providing access to the internal chamber, and a cover connectable to the sidewall to enclose the internal chamber. The sidewall defines a first surface section adjacent one of the at least two ports, a second surface section adjacent another of the at least two ports, and a radiused transition section connecting the first surface section and the second surface section and configured for reducing frictional drag of a cable pulled though the internal chamber. The first surface section is spaced apart from the second surface section to increase a volume of the internal chamber.
