Abstract: The invention is directed to an apparatus for performing the remotely-manlated installation and removal of a pass-through conduit unit into and out of a channel formed in a partition wall. A feed assembly is part of the apparatus and includes a plurality of parts assembled to form an elongated body in the channel. An articulated coupling such as a ball joint couples the conduit unit to the elongated body. A drive is operatively connected to the elongated body for displacing the latter in the channel. A crane has a holder for holding and remotely manipulating the conduit unit as the latter is installed or removed from the channel.
