Installed a 40" velcro strap to the sink side panel for securing 2 TV tray tables. Tables fit perfectly and are easy to access.

I used (4) finishing washers + (4) 1/4-20x1/2" round combo with nuts, placing two (through the strap and sink panel) near where the top of the trays would be, and two near the bottom.
