Does anyone have experience with the mounting a mirror using the type of rails (Rite-View®) and brackets shown in the pictures below? It seems fairly straightforward but I have a few questions:
What is the correct position of the mirror? Should the bottom of the mirror be installed flush with the dresser top or does it not matter? Based on the screw marks on the rails it looks like the previous owner had this raised up a bit but I've not seen one like pictured like this before.
What is the correct position of the mirror rails? There is a slot and some holes at each end that look like they could be intended to interact with the brackets screws in some way. It's hard to tell.
Is there a "correct" alignment/position for this hardware or is it solely down to personal preference?
