This unit is used to help pass a pigtail or patch cord through convoluted tubing where multiple optical fibre cords have already been installed. It consists of an LC connector female half with a 3-metre flexible wire lead attached. The flexible wire lead is housed in a plastic tube to prevent accidental shorting out of non-insulated power conductors. During use, excessive pulling force and fibre strain should be avoided. The installation should be achieved in a smooth, very low pulling force, jerk and snag free manner.
