This fiber optic tube insertion tool is specially designed for fiber optic installation and splicing. It is used to easily thread fibers into protective tubes. With a telescopic rod design, it retracts to only 320 mm for easy carrying and storage, and extends up to 2222 mm in total length, easily meeting long-distance tube insertion needs. It is suitable for protective tubes with a diameter of 3-6 mm. The top is equipped with a standard threaded connector, allowing it to be used with different threading heads. Its non-slip design allows the fiber to slide more smoothly into the protective tube.
