How to change the cord of a blind

Whether due to the passage of time or to wear and tear, the blind cords deteriorate and lose their effectiveness. As soon as you notice that they become frayed or weak, it is advisable to replace them to avoid possible breakage and to keep them working properly. Below, we show you everything you need to know about how to change the cord of a blind.

Cases in which the blind cord does not need to be changed

Below, we show you in which cases no need to change the rope of a shutter:

When the shutter does not go up or down fully

To solve this problem, it is necessary to open the roller shutter drawer and remove the mechanism located between the slat panel and the shaft so that the rope can be completely extracted (taking care not to lose it if it is picked up).

After this, you have to rotate in the opposite direction to the shaft disc so that the rope is well collected. When you reach the stop, put the mechanism back as it was and check that it works correctly.

The shutter does not stay up, it falls under its own weight.

It can happen at a time when the rope is not held by the pick-up flange. To solve this problem, it is advisable to open (if it is a hinged exterior) or remove the dustpan from the wall.

We have to make sure that the rope passing through the slits of the pickup has a small pestana and causes it to jam.

Consists of repair or close that tab to be in the place where the rope passes and not to close it completely, since, if the rope does not have space to pass, it will not slide correctly.

In case these are not the problems, it is convenient to complete replacement of the shutter beltThe mechanism can be disassembled by opening the box, disassembling the mechanism and also the dustpan. But we will tell you more about this later.

The materials and elements we need to change the tape of a shutter are:

• A tape of the same width as the previous one (to avoid jamming).
• A wooden wedge, screwdriver or something to block the shaft.

Changing the cord of a PVC shutter

Blinds are mechanisms made of PVC or aluminum that help us to protect our home from light and heat. The The most common models are the roll-up models and we discuss the steps to change the shutter belt.

1. Start the work by raising the shutter completely and fasten it with a pair of clamps.
2. With the help of a screwdriver, we remove the cover of the shutter drawer.
3. We remove the knot that holds the old belt to the upper pick-up or shaft.
4. Subsequently, the new strap is introduced and, after knotting it, it is wound on the drum, turning it several times.
5. After this, we insert the new strap through the slot in the cover to allow it to come out of the box.
6. After this, we fasten the tape and release the clamps and lower the blind completely.
7. At this point, it is necessary to loosen the lower catcher and remove the rest of the old rope.
8. Remove the damaged rope, carefully holding the winding device so that the spring inside it is tensioned.
9. After that, with scissors we make a small hole in the new tape.
10. Then, we insert the ribbon with the small hole inserted in the hook and let the spring pick up the ribbon.
11. Finally, we put the dustpan back in place and screw it carefully, making sure that the rope remains tight.
12. In this last step, we only have to check that the shutter works correctly, that it goes up and down without problems. In a simple and easy way, we have solved the problem.

How can we calculate the length of a blind cord?

When we change the cord or tape of a shutter, we usually have the doubt of how much it measures for the mechanism to work properly. In this case, we can calculate the measurement in several ways:

• The easiest and simplest is measure the length of the old rope and buy it with the new one to match.
• Another way to do this is measure the length from where the rope exits in the drawer to the part of the pickup where the cord enters and multiply that measurement by four. This way, you will have the exact measurement for the blind cord.
• The required rope can be calculate by valuing the length of the window lengthwise (frame included). The size of the tape will then be between 2.5 and 3 times more than that of the window.

As you can see, how to change the cord of a blind is very simple and you can do it without having to ask a professional for help every time the rope comes off or gets damaged and needs to be replaced. If the rope is broken or damaged, these steps will be the perfect guide to replace it with a new rope.
