Without a doubt, Sir knows better than this girl.100% agreed. Very simple and effective. I only doubt, from a pure engineering point of view, about aluminium angle if you want to put the full body weight on it. Either is a big angle or I suggest a steel angle (maybe stainless, easy to clean at the "end"
However, stainless steel is expensive. Why not a demolition reclaimed rusty cast iron angle?
Also, the rusty surface may have a high roughness coefficient to add to the joy of the experience...
