Cable Threading Tool: Quickly and flexibly route cables through empty conduits, drywall, floor and ceiling walls, and more. Two Cable Puller Types: Two different sizes of cable pullers can be guided through cable pipes of various diameters. This innovative design allows for smooth passage through enclosed spaces, insulators, and obstacles, letting you pull the bottom cable to your access point. Simple and Effective Use: The puller has holes for attaching the pull line; simply thread the line or a special cord through the small holes and secure it. Then, leave the magnetic pullers on both sides of the pipe or from the outside of the pipe to pull the line where you need it. Time-Saving and Less Damage to Pipes and Walls: Using these tools saves time on repeated work at the ends of pipes or on both sides of partitions. Plus, you no longer need to make multiple holes to run wires, and you can easily pull and install wiring without damaging pipes or walls. A Gentle Reminder: The magnetic adsorption capacity may vary depending on the thickness of the pipe, partition, or floor (recommended thickness less than 1 cm). Use appropriate pulling force to reduce the speed of movement to ensure greater adsorption. Package Includes: 1 color-printed box. 1 set of 4 pullers. Weight: approx. 110 g (including packaging).
