This is a pack of 6 replacement docking ports for the 1/350 Refit Enterprise/Enterprise A. Each port is accurately detailed based on the original closeup set from The Motion Picture. There is one for every port on the ship including one on the bridge module, two for the torpedo launcher, and two for the engineering section, plus one for good luck. Simply drill out the existing ports and glue these to the inner hull. Each port has two notches to allow lighting the door like in the film.
