I need a Schuko socket similar to Peha 00909394 that can be fixed inside an aluminum tube with an inner diameter of approx 53 mm. In addition to that I need a Schuko plug that can be fixed inside the same tube (other end of the tube) using screws or another way to fix the plug/socket inside the tube. Can you provide a custom plug and socket that can be secured inside the tube using two or more screws? In the end there should be at least two tubes that can be stacked on top of each other.
