Basco Shower Door Classic Sliding Fits 40-44 inch opening, Clear Glass, Oil Rubbed Bronze Finish

Width of opening is 42.5 inches. Will this frame adjust?

The item wait says 3.2 pounds. This does not seem possible. Please confirm the actual weight.

Missing parts on 3500-44sclsv where do i request them from manufacturer?

65.5 in height seems very short! Is this for a bath tub? The picture displays a walk in shower. Im not finding taller doors for a 40 wide walk in.
