Last on the list is the USA based Hunter Douglas. Although USA based, they are the most difficult to obtain any information from.
For example in the link above, the picture does not show a proper blackout blind. However, by scanning the link to their PDF file on the RB500 system, I located a mechanical drawing of a proper blind system, the RB500 5-51. However, there is no other mention of that product on the website, so it is a mystery if it is actually available.
I have an e-mail out to them, not asking if they ship to the USA, but to see if the products are actually available for purchase. There is no ordering or purchase information on the site.
