Overall I must say that the panel blinds are fantastic. Very happy with the results and the amount of light they block out (we got the block out fabric but other fabrics are available that let light though). Below is the final installation with and without the blinds drawn on one of the sliding doors.
This is how the blinds are packaged for mailing - they come in two boxes. The long slim box contains the glide system railing and the bigger box contains the rest of the hardware and the panels.
The rails are meant to be mounted on these plastic clips that click into place. At first I thought this wasn't fantastic but after mounting them I really appreciated the fact that you could detach the rail later. Because the clips are plastic there is also some room to move the rail around after it's mounted into place.
These clips can be attached directly into the ceiling but it's a better idea to attach them to the metal brackets that are supplied. We had to cut these brackets down to fit flush with the door frame, that's just for cosmetic reasons and we could have left them as is.
The brackets attached to the metal door frames and then the rail clicked into place.
Then it was just a matter of attaching the weights to the bottom of the panels and attaching the panel to the rail. The panel is attached using velcro, it just sticks in place!
That's it! The only downside is the blinds are 600mm in width and so always block out that much of the door, but in my case that is not a big deal.
