How to Assemble and Install Louverdrape Cellular Shade Cord Locks

Repair ID: 181033


Introduction

This guide will show you how to assemble and install a cord lock that is used in Louverdrape cellular honeycomb shades. This cord lock uses 0.9mm diameter string. These cord locks come in two sizes but use the same internal parts. The small lock measures about 1 ¾” and the large lock measures about 2 ½”.

The cord locks will arrive unassembled. You can assemble it for use on either the left or right side. It’s much easier to put the string through the lock when it is unassembled.

To put in a new cord lock, your shade will have to be down out of the window and laying on a work surface. Pull the shade all of the way up and hold it together with rubber bands if needed. Remove all tassels and condensers off the string as needed.

Tools Needed

Needle Nose Pliers

Step 1 – Let’s look at how the cord locks are assembled. This example shows how to assemble one for the right side. Put the body of the cord lock on a flat surface. Start with the opening of the cord lock facing away from you.


Step 2 – Use needle-nose pliers to hold the knurled (ribbed) roller and place it on the right side of the opening. You may need to keep your finger in front of it to keep it from rolling away. This roller is small and it may take a few tries to keep it in the correct position.


Step 3 – Snap the plastic insert over the top of the knurled roller with the opening of the insert facing right.


Step 4 – If you need to take the lock apart, use the needle-nose pliers to rotate the plastic insert away from the lock body.


Step 5 – Reinsert the smooth roller into the insert if it comes when you remove the insert.


Step 6 – Let’s now assemble the lock for use on the left side. Again, start with the opening of the cord lock body facing away from you.


Step 7 – Use needle-nose pliers to hold the knurled (ribbed) roller and place it on the left side of the opening. You may need to keep your finger in front of it to keep it from rolling away. This roller is small and it may take a few tries to keep it in the correct position.


Step 8 – Snap the plastic insert over the top of the knurled roller with the opening of the insert facing left.


Step 9 – This is what the cord locks look like when assembled for both the left and right sides.


Step 10 – Now, let’s install the cord lock in the shade. Remove your blind from the window and remove any tassels and/or condensers from the string on your shade. First, remove the old cord lock from the shade. Compress the tab on the top of the shade with the end of the needle-nose pliers so that you can pull the lock out from the headrail


Step 11 – Remove the string from the old cord lock. The string may keep getting locked inside of the cord lock, and the cord lock may need to be unlocked several times. You may need to use the tip of the needle-nose pliers to move the knurled roller out of the way so the string can move freely.


Step 12 – Now, we’ll insert the string coming out of the shade into the cord lock. Start with the cord lock unassembled. Insert the string over the grooved portion of the plastic insert and then through the foot so that the string is running over the smooth roller. Set this piece aside with the string in it.


Step 13 – Lay the cord lock body on a flat surface. Use needle-nose pliers to hold the knurled (ribbed) roller and place it on the side needed. You may need to keep your finger in front of it to keep it from rolling away. This roller is small and it may take a few tries to keep it in the correct position.


Step 14 – Snap the plastic insert over the top of the knurled roller with the opening of the insert facing the side you need.


Step 15 – Now it’s time to put the cord lock back into the headrail. Pull the strings through the cord lock making sure that they are not tangled or overlapping inside the headrail. Push the lock in until it is seated fully in the headrail.


Step 16 – Test the cord lock to make sure it operates properly. You may need to rehang the shade in the window for this test. Pull the string to the outside of the shade to lock it in place. Pull the strings toward the middle of the shade to unlock them.
