Dear forum community,
We have a separate entrance in our apartment with a steel frame. You can find the dimensions in the pictures. I would like to install an electric door opener there. Can someone help me? Most openers are 28 mm deep (1.1 inches) and do not fit in the frame with 20 mm (0.8 inches).
Does anyone have an idea?
Best regards and thanks!!!
