The huge number of options are all clearly explained, so as with my previous experience, I was able to order exactly what I wanted - exactly to fit the framing in my garden room. My previous order all arrived exactly as specified, and when in my inexperience I needed some additional advice in connection with fitting, they were very helpful on the phone. I expect this order will be just the same, except that hopefully I now know how to fit them so maybe i won't need the telephone support so much this time! The pic I have uploaded shows the previous items I bought, the door and Windows. I havn't removed the protective tape yet in the pic, to avoid scratching as other work is done, but they will look great once all revealed. The door is low threshold for wheelchair access, which is another of the many options and works really well.
