How to Restring a Vertical Blind Headrail

Video ID: 381006


Introduction

When the string on your vertical blind becomes frayed or breaks completely, it is necessary to restring the blind. These instructions show how to restring your vertical blind headrail. The blind shown is a common vertical blind with a one-way draw. The parts in your blind may look different, but the techniques shown will apply.

A Note on Safety

Kids can strangle in blind cords. To make your blinds safer for kids, keep cords out of reach and secure cord and bead chain loops. To learn more, please visit our child safety guide.

Tools Needed

Scissors
Phillips Screwdriver
Needle Nose Pliers
Lighter

Step 1 – Measure the blind.

  • Use the following formula to determine the amount of string needed:
    2x the width of the blind + 2x the length of the blind + 5 ft.
  • Cut the length of cord needed.
  • Remove your slats from the blind by using a flat object like a plastic card to release the slats from the clips.

Step 2 – Remove the headrail by pushing up on the bracket tabs on the backside of the blind. Place the headrail on a flat surface.

  • Remove any cord weight or tensioners from the blind chain or cord.
  • Pull the cord free from the blinds with your pliers.
  • Cut the ends knots off of the cord.

Step 3 – Use the lighter to melt an end of the new cord to the old cord.

  • Roll the cord to meld the ends together.
  • Pull the cord through the blind.

Step 4 – Tie a knot at the end of the new cord so it won’t pull through the blind.

  • Cut off the old string.
  • Tie a knot and cut any excess cord.

Step 5 – If your cord is completely missing or broken, remove the control end.

  • Use the wire restring tool to feed the string through the carriers and control end.

Step 6 – Feed your cord through the eye of the wire and pull through.

  • Feed the cord around the wheel on the idle end.

Step 7 – Feed the wire restring tool through the last carrier. Pull the string through, and tie a knot.

  • Feed the wire back through the carriers and control end.
  • Pull the cord through the control end.

Step 8 – Insert the wire through the other hole in the last carrier, and pull the cord through.

  • Tie a knot, and cut any excess cord.
  • Test your repair by pulling the cord.

Step 9 – Some carriers vary on the brand and may have different cord paths.

  • If the cord needs to be fed through a small hole, melting the end of the cord will prevent fraying.
  • Feed the cord through the carrier, and tie a knot at the end of the cord.

Step 10 – Reattach the control end.


Step 11 – Reattach any cord weights or tensioners to the cord and chain. It’s important to keep all loops tied down securely for child safety reasons.

  • If necessary, adjust the length of the cord by pulling the cord through and tying a new knot.
  • Reattach your blind to the brackets by inserting the front of the headrail into the bracket and rotating the headrail up and back.

Step 12 – Reattach your vanes to the blind.


Step 13 – Test the repair by pulling the blind open and closed.
