Protective Cover for Cable Components

A protective cover for cable connectors and methods of fabricated the protective cover. The protective cover comprises a tube open at one end and substantially closed at the opposed end by an end cap. The end cap bears at least one opening formed therein. The protective cover has a foil outer layer, a soft felt inner layer, and an insulating fiberglass core between the outer and inner layers. The tube is made by overlappingly rolling and bonding a section of foil-backed fiberglass. The end cap may be separately made, made as part of the pattern for the tube, or may be formed by cutting pointed teeth into one end of the tube pattern and bonding them generally perpendicularly to the length of the tube.
