A good way to protect the cutting and speed up the cutting calusing and subsequent rooting is to sprinkle/dip the cutting in either rooting powder or cinnamon. Rooting powder is the better bet for something you want to root, cinnamon is perfect for where a cutting has been taken from as you probably don’t want your established plant to start sprouting roots half way up
A quick suggestion as those don’t look like nylon lock nuts; grab yourself some medium strength locktite and put a drop on each of the threads otherwise that frame will slowly become loose due to thermal expansion/contraction cycling
