We're having a problem with our Hunter Douglas vertical blinds separating when we pull the cord to advance or retract the blades. We've taken the unit down and what's happening is one of the metal "fingers" that interlock to hold the blades together (so they work in unison) keeps separating and we can't get it to lock back together.

Does anybody know how we can fix these vertical blinds?

Thanks!
(Looking forward to hearing from anybody )

 

If, ??? I'm reading the description of the problem you gave correctly then I had a similar problem. My solution was some hot glue on the fingers.
