Everything about the door is good with the exception of the bolts that hold the railing to fixed panel.  The length of the bolt is not sufficient; it does not catch the thread in the railing.  I had to remove the plastic washers to gain another millimeter or so in order to catch the thread.  Now I am risking of a crack because the metal is touching the glass.  Other than this deficiency, the unit works great and the installation instructions are very detailed and right on.
