My strong hold on the table. That's all it takes, they don't move. I love that they included 2 sets of screws with different diameters for the joystick and throttle. I have X56 Rhino. They were processed very well. Everything runs as it should, and apart from the height, you can set a horizontal angle if you want. There are pan head screws where needed, good. They were worth their money, love being able to unplug, flip the clamp and put them away when I'm done playing. The clamps holding them to the table snap into place and remain until released.
