ABSTRACT:
An apparatus and method is provided for protecting, installing and removing a fragile device having a screw threaded mounting end. The apparatus includes a housing surrounding the fragile device having an open end with a screw threaded portion which is threaded in a direction opposite to the screw thread mounting end of the fragile device. An end ferrule is attached to the mounting end of the fragile device and has a screw thread portion adapted to threadingly engage the screw thread portion of the open end of the housing. The method is practiced by inserting the fragile device into the screw threaded open end of the housing and threadingly engaging the ferrule with the housing in a first direction to a desired level of torque. The screw threaded mount of the fragile device is then threadingly engaged in a screw threaded mounting hole by turning the housing in the same direction until the fragile device and the ferrule seats. The housing is then removed from the fragile device by continuing to turn the housing in the same direction until the housing is threadingly disengaged from the ferrule.
