I don't know which rocketfish you chose, but the one that has the plugs facing left and right should work. My TV is 50 inches but I also mount the sound bar to the TV so it might be close in weight to the 70 inch. I really can't imagine the protector being a problem. I have a traditional protector and the Direct TV mini box on the wall next to the hinged wall month location. Even with the plugs pointing away from the wall it does not cause a problem with the TV. Good Luck.
