Parts Related To This Repair:
Vertical Carrier

These instructions are for one-way cord draw L-60 headrails.

Begin by removing louvers from vertical headrail and lay them flat on floor. Remove vertical blind from brackets and place on a flat work surface. Pull chain to where ends are even.
1. Remove idle end cover and place to side. 2. Loosen Allen screw (1/16") on control end.
3. Pull the cord ends away from the cord carrier and snip ends close. Cords can then be pulled out and away from carriage and idle end with tilt bar still attached and carriers can be removed from headrail. (a) Take care not to lose the spacers located on the control end of the tilt bar.
4. To remove carriage units from tilt bar, another Allen screw (5/64") will need to be loosened and removed from between the first two carriage units. (b) Notice the notches made from the screw on the tilt bar. This is where the Allen screw will need to be returned.
5. Locate the carriage unit(s) that need replacing. Turn over and twist the top most pigtail from the bottom of the carriage unit. 6. The other pigtail will need to be popped off using a flat piece of metal or small flat tip screw driver. Insert flat tip on top of pigtail and press tab down and push in to release pigtail from carriage unit.
7. To replace carriage unit in the carriage assembly, place (c) first pigtail into notches on bottom of carriage unit, then (d) place the second pigtail on top.
Holding both pigtails in place with your finger (e), pull the first pigtail until you hear a click. Both pigtails will be caught into the tabs on the bottom of the carriage unit. 8. Insert the tilt rod back through the carriage units.
9. Slide assembly back into headrail. Remember to place plastic ring with Allen screw back between the first two carriage units. Also remember to place the plastic spacers back onto the tilt rod before placing tilt rod end into the control end. Tighten smaller Allen screw. 10. Thread cord back through each carriage unit.
11. Thread one end of cord out through idle end and back in around pulley wheel. 12. Thread each cord through the cord carrier, threading from top, and put knots on each end.
13. Replace control end into headrail, snugging onto tilt rod. While pushing tilt rod from idle end into headrail, tighten down Allen screw on control end. Upon completion, hold headrail upright, carriers pointing down, and pull the chain to realign carriers. Pull chain all the way in one direction until it doesn't move anymore. Give it a firm tug. It will sound like gears are stripping. Pull chain in the opposite direction and repeat the firm tug. Reinstall into window opening and reinsert louvers.
