The replacement canopy was not exactly a perfect fit for our grill gazebo.  The frame had 4 extra hold down supports that was missing on the replacement canopy. So I asked for a replacement with pictures of what we needed.  The second canopy was exactly like the first.  Since we needed a canopy, we tried the first replacement on the frame.  A corner tore during installation - even before we had the whole top on the frame!  The second replacement was much better and fit well.  On both the first order and the second order the vent top was too small.  So neither really fit correctly, but we are making due at this time.  We are entertaining in the backyard and one of the tops will do for now.
