If you have corded vertical blinds that have a centered master control gear running through the center of the gear channels than the blinds can be converted. All you need is a master wand control, a wand, and about fifteen minutes spare time to make the change. First loosen and remove both end brackets. Next remove the gear mechanisms from inside the end caps (usually held in place by a keeper). Discard the inner gears and blind chain. Behind the blind gears opposite of the corded end you will find the cord is knotted or split weight clipped. Cut off the knots or split weights and remove the entire cord. (Watching the youtube video I made on this will help you better understand the steps involved.)
Next find the keeper and make sure it is installed in the proper place just in front of what will be the very last slat. If it is in the wrong place remove it and install it in the proper place. If the blind slats are curved the convex portion should go to the back. Next install the rear end bracket. Now slip off any guides in the way of the first stem control and remove about the first four slats to give better access. Next slide out the main gear a bit and some of the blind stem controls enough for you to use your screwdriver more easily.
The new master control will have two screws that pass through it linking it to a stem control. Remove the two screws and discard the stemless stem control. Next slide the master wand control onto the main gear, screw holes facing towards the blinds. Next slide the first stem control up against the master control and use the two screws to link the first stem control to it. Now re-install the guides previously removed and reattach the end cap.
Attach the blind wand, reinstall your four slats and your ready to test the blinds for proper rotation. If you can’t get a full rotation you may need to pop each stem over a couple points. I will try to cover this better in a future video so subscribe to my Youtube channel if you want to be one of the first people to see that video (your subscribing helps support and encourage me to make more videos and write more blogs).
As I have mentioned before do be careful as the blind head rail is very sharp unfinished metal and cuts flesh just a bit to easily. The video on Stems and Gears should help a bit in understanding the way vertical blinds work.
