Perfect Flexibility and Rigidity: The insertion spiral is made of plastic-coated steel, featuring a non-conductive plastic coating structure that is durable, flexible, and offers good resilience. It won't break when bent, providing strong pulling force, resistance to aging, and less abrasion. 360° Accessible Wheel Head: The head of the electrician's probe is 360° usable and easy to pass through bends. Its unique connection makes it durable and simple to use. The spring roller allows for easier insertion and is faster than regular wire. Easy to Use and Save Time: One side connects to a cable. The red wire cap prevents the wire from loosening during pulling. The other side connects to the fish tape, ensuring the wire and fish tape are tightly joined. Save time by quickly pulling cables and multiple wires. Application: Cable insertion aid for conductors or power cables in cable protection tubes and conduits. Ideal for pulling cables through pipes, conduits, and ceiling cavities.
