I have really tall doors, will this still work?

Yes it will, the Height of the panels are adjustable from 199cm up to 211cm

For taller doors, we have extension pieces available to extend your height. 

Each extension piece adds 12cm in height, the taller you need the panel the more extensions you get. See extension pieces here.

This is the adjustable top part 

And this is the adjustable top with 1 extension in place.
