How to stretch a corrugated cable without a string: a life hack from electricians

Required inventory

For this manipulation you will need:

  • vacuum cleaner;
  • regular or masking tape;
  • strong thread or thin rope;
  • candy wrapper or small piece of paper.

Here is the main requirement for the thread. It is best to choose a synthetic, nylon thread. It has increased strength and will not break when pulling the wire. The length of the thread must exceed the length of the corrugation.

What should be done

When using this method, it does not matter how long the corrugation will be and how it is located.

  • Tie a wrapper or a piece of paper to one end of the nylon thread. This part will act as a sail and move the thread in the direction of the air flow.

  • Insert one end of the corrugation into the vacuum cleaner tube. Seal the connection with adhesive tape.
  • Insert the thread with the tied paper into the other end of the corrugation. The free end of the thread must be glued with tape of the same part of the corrugation. This is to prevent the vacuum cleaner from sucking in all the filament.
  • Switch on the vacuum cleaner. The thread with the "sail" under the action of the air flow will rush through the corrugated pipe to the vacuum cleaner. When the end of the thread enters the hose of the vacuum cleaner, turn off the device. The thread is threaded through the corrugation.
  • Next, tie a wire to the thread and pull it through the corrugated pipe. Done!
