The materials look great but all of the slats come separately -  we could get them to slide in on one side but could get the other side to slip into the pre-cut out hole.  We tried laying it down, we tried standing it up.  We tried putting the four “framing” pieces together and still we could not get the slats to connect on both sides.  So we signed up for an installer to come to our house.  Hopefully s/he can get it done!
