I 've noticed underneath my slides that a plastic strip guard had come loose. I need to replace it but can not find them anywhere. The wires it was protecting haved rubbed the sheathing so bad that copper is showing. The plastic guuard is about 4" wide by 1/4" thick and is about 3-4 feet long tied to the wires with cable ties. Does anybody know the correct name of this guard and where I can purchase them?
