I am offering a guard rail made of tubular aluminum.
This railing stands 3 feet high.
It is 50 inches wide.
The tubular aluminum is 1⅞" in diameter.
The metal is ⅛" thick.
The inner diameter of the tube is slightly more than 1 9/16" in diameter.
This can make a good ramp rail, or skateboard rail.
This rail has been used.
It has some scratches and minor stains, but it has no dents or breaks.
It has been scrubbed clean.
Removing any remaining stains would require sanding, which will make the metal thinner and weaker.
I have only one.
I do not have access to more.
