This item is really well designed. It is not a cheaply designed and constructed item as has been reviewed. Imagine my amazement when I opened the parts bag and found not only the bolts (both for wood and masonry) but also a hammer drill bit. Fortunately I do have a hammer drill ... and if the bit would have worked in my hammer drill (dewalt) then I wouldn't have needed another hammer drill bit (which I had).The product could have one improvement. Please make the rail mounting points adjustable so they could be moved up and down on the rail. By making the mounting points movable the posts could be more ideally located on the floor.
