Abstract: A method of manufacturing a prosthetic socket having an access port that employs a housing with a cylindrical extension. The method includes the step of molding a shell over a socket model and a mold dummy to form an intermediate port. The method additionally includes the step of trimming the intermediate port along a trim line passing through a cavity defined by the mold dummy to create a circular opening in the shell. The mold dummy has a first diameter generally conforming to a diameter of the cylindrical extension of the housing. The method further includes the steps of passing the cylindrical extension through the opening and securing the access port to the shell.
