Arrived well packed.  Three glass panels need to be assembled with 32 allen head screws.  Do yourself a favor and get an allen head screwdriver or it will tank an eternity! :)   Better quality than expected!  Matches our windows perfectly.  The soft-close mechanism installation instructions are a bit confusing.  Study the the instructions later in the booklet to understand how the entire thing works.  The closures work very well and keeps the door closed as an added bonus!  We used it to complete out wine room!  Terrific buy for the money!  (BTW- I had the framers back the header area to accept the top rail bolts when we built the house, so no header board was required)
