Kung ako, gagamitin ko yung screw holes for the wall mount, kasi yon ang matibay.
2 screw bolts, 2 pairs metal washers. Screw the bolts with washers on the TV's wall mount screw holes. Tie a thin solid wire on each screw bolt in between the washer pairs, then tighten. Connect the ends of the wires to the rack with a metal screw eye.
Why use double tape on the back panel, e may matibay na screw holes na doon.
