Yes...you are right.
For safety, I will add 2 more bar holder if select option 1 else add 1 more for option 2... .
Btw, possible to post the picture of your mazarra stand here?
Here is my thought of MY 2 Lite stand holder design, 1st is double bar and 2nd is single bar (Dimension not confirm yet).
I personnelly prefer single bar if it can withstand 1.5kg holding weight..
Please comment.
