Cable guide tool: allows you to quickly and very flexibly route cables through hollow pipes, Placopltre walls, floor and ceiling walls, etc Two shapes of cable pullers: two cable pullers of different sizes that can be guided through cable tubes of different diameters. This innovative design allows smooth passage through closed spaces, insulators and other obstacles and allows you to pull the cable from the bottom to your access point Simple and efficient use: the extractor has holes for fixing the pull cord, just pass the cord or a special cord through the small holes and fix it, then leave the pullers on both sides of the tube or plate and gently move the extractor around the outside of the tube to route the cord where you need it Time saving and less damage to pipes and walls: by using cord grips you can save time for repeated work on pipe ends or both sides of bulkheads. In addition, you no longer need to cut multiple holes or holes to lay wires, and you can easily pull and install wires without damaging pipes or walls A warm reminder: influenced by the thickness of the tube or partition, the floor, etc. (recommended thickness less than 1cm), the adsorption capacity of the wire puller may vary, appropriate traction to reduce the speed of movement to ensure greater adsorption Packing: 1 box printed in color. 1 set of 4 extractors. 1 user manual in English.
