The hardware seems very sturdy, but the instructions could use an update.  I highly recommend posting the instructions on the sales information page.  Then add in important thoughts such as door heights and the fact that there is no clearance for trim around your doors.  The bolts are too long and require more space that is unnecessary in the design.  I recessed the bolts on the wall side to help with clearance, but still needed to add a ledger strip to the wall to clear the moulding.  I also went to the single track as the space was too great for the outside door to keep noise out of this room.  FYI... the outside door hangs 1/2 inch higher when you follow the instructions for the hardware.  As you see, I ditched the outside hardware and kept everything on the same track.  Of course I found out all this information along the way and had to repair holes and repaint the wall after removing the outside rail.  Like I said...  good product, but needs to be more clear on the specs.
