Great door, especially for the price to include all the hardware.  Was a little intimidated when I opened and saw all the pieces.  It took several hours to assemble the door and hang the track system.  It’s time consuming but bring your patients and an extra set of hands!   I did use a wood mounting  board instead of anchors.   I am using this to cover a laundry closet that had a bi-fold door previously.  I will be adding the extension bar so it opens a little wider.
