The rails aren't too difficult to resize

These use the thinnest, flimsiest rails I've ever seen on a hanging file frame

Top rails turned in.

People complain a lot that the adjustable rails cannot be snapped to length, I have tools and it was not hard to score them with a triangular file and break to length.

It is also hard to assemble the frame when the rails want to lean out.

Slots for side rails do not align properly, therefore the side rails are canted at an angle2) Screws for securing side rails are tapered round-head, wide-slot screws that require an abnormally THICK slotted screwdriver

So, I purchase this rails to hang my files.

After screwing together the whole thing is crooked and if you try to align and straighten it out then the rails pop out and the whole assembly falls apart.
