An apparatus for protecting equipment in a wellhead from exposure to fluid pressures, abrasives and corrosive fluids used in a well treatment to stimulate production, includes a mandrel to be inserted through the wellhead into an operative position. The apparatus further includes injectors for reciprocating the mandrel to and from the operative position. The injectors are connected on their top ends to a connector plate that provides a support platform to permit equipment, such as blowout preventers, wireline units, coil tubing injectors or the like, to be mounted to the top of the apparatus.
