The tools you’ll need for this repair are
– Scissors, a Phillips & flat head screwdriver, a tape measure, needle nose pliers, and a
restring needle. Measure the length and width of the shade,
then cut the new strings you’ll need for this repair.
Twice the length plus the width is the formula used to ensure proper string length.
Loosen the Phillips screws on the bracket behind the shade 2 full turns. The shade should
come out towards you. Remove the shade from your window and lay
it on a flat, covered surface. Remove the condensers and tassels and set
them aside. Remove the cord lock from the top rail.
Remove the end cap from the top rail. Slide the top part of the top rail off.
Flip the shade over. With the pliers, pull the string with the
pocket and ferule until it releases. Then pull the ferule off and set aside.
Pull the old strings out and discard. Thread a string the needle and pull it through
the fabric. Thread the string through the ferule, leaving
about a one inch tail and pull through to seat.
Repeat for the other strings. Flip the shade over and install the string
guides. If the guides show any wear, they should be
turned so the string rides on the unworn side, or they should be replaced.
Slide the top rail on being careful not to snag the fabric.
Replace the end cap. Thread a string through the cord lock and
the latch as shown. Carefully slide the cord lock into the rail
making sure not to snag the strings. To rehang the shade, slide the top front portion
onto the bracket first. Make sure the front tab of the bracket is
seated in the slot at the front of the headrail. Then push the shade back until seated. Tighten the Phillips screws to secure.
Test your repair. With the shade all the way up, cut the strings
a few inches below where your shade should stop when it’s lowered.
Install the condenser and tassel.
