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


Step 1 – Mark the lift string.

  • With the shade raised all of the way up, mark the strings approximately 2” below where your shade should stop when it is fully lowered.

Step 2 – Attach one of the strings to each half of the condenser.

  • With the condenser separated insert a string into the top of one half of the condenser.
  • Slide a washer onto the string and pull it past the mark on the string until it hits the condenser.
  • Tie the string off at the mark with a double knot to ensure the knot won’t pull through.
  • Repeat with the other half of the condenser.

Step 3 – Test the shade to make sure it raises evenly.

Step 4 – Trim off the excess cord.

Step 5 – Attach the pull cord.

Step 6 – Snap the two halves of the condenser together.
