This housing is designed for 2/4/8 Arcade Joysticks. The one I used has a green restrictor plate on the back but others might fit too. Installation into the BEKANT Table requires to open the original gray controller and solder 3 wires down/up/common where the stock buttons connect. On the joystick side you wire it to connect either up or down to the common connection.
