This was a bit difficult to make it stable.  I had to purchase more self-drilling screws and placed them at every cross trellis after the end supports separated.  Instructions were ok but not the best.   It is narrower than I expected.  I need to pay attention to the measurements.  It is lightweight.  My next trellis will come from a garden center.  Much more cost-effective than this one.  All that said, my Tombstone Rose looks very nice climbing its trellis.
