How to Replace a Venetian Blind Cord How to Replace a Venetian Blind Cord

Snapped or breaking your venetian blind cord may seem like a big problem but it is actually easily remedied. These cords run a standard length, depending on the size and shape of your blinds, and can be replaced with a little time and patience.

Step 1 - Remove the Caps from the Old Cord

Use a screwdriver, or simply remove the blind locks on the left and right of the unit, and take it down, so you can work on it without much effort. Next take the cap off one end of the old venetian blind cord, and watch how it turns around the wheels and pullys as you pull it out of the unit. As you can see the gravity lock is on the outside of the cord so that when you let go, it will bite into the cord, preventing the shade from falling from its locked position. The second thing to take into account, is how the cord moves through the track to the other pulleys and attaches to the blind. Look closely at the pattern, and how the cable goes in and around the various wheels, and pulleys. You will want to remember this, so that when you string your new line in, it does not snag or get bunched up inside.

Step 2 - Remove and Measure the Old Cord

Once you have the old venetian blind cord removed, you can then measure its length so that you can replace it with the right size line and avoid it being too long or short. Most of these cords are made from polyester or vinyl material, to prevent them from snagging or coming undone over extended periods of use. Be sure that the line does not have any knots in it, that may get caught or snagged in the blinds pulley system.

Step 3 - Restring the New Cord into Place

Once you have all the other steps completed, and you have the correct length cut for the replacement venetian blind cord, you can start to restring it through the pulleys. Generally, you would start at the back and move your way to the latching mechanism, that is gravity operated on the end where the cords drop out of the unit toward the floor. Start by stringing the back ends into position, and then run them through the separators until you reach the rolling lock. Be sure that your line is moving through this eyelet on the inside of the roller so that later when you go to lock the blinds in an upward position, the wheel will bite them properly. The important thing here is to remember the exact path that the old cord took, to prevent it from snagging or getting caught when it is in use. Once you have the line in place, slide your caps on and tie a knot in the ends, this prevents the line from getting pulled up through the rollers.
