Okay I have finalized the decision to install on the magazine rack. Making spacers out of cutoff recycled pallet wood that is sucking up space in my shop.
2 individual dual port USB 3.0 chargers with waterproof covers and plastic mounting plate, mounted to the spacer. Need to drill the pilot holes for the mounting screws next.
Rear view of the assembly.
View of the assembly with waterproof covers raised to show the ports, if you look on the right side of each panel, there is a small on / off button, no need to control elsewhere.
Not sure I am going to use any sort of finish on these. If I do, I have a small can of Minwax American Walnut that should be close enough to the factory faux wood finish.
I might just trim the fabric away from the work area and, well make it work. We will see.
