It is truly a building material maker. The mounting dimensions were also tight, and the mounting and fixing method also corresponded to various floor reinforcement patterns. It worked for 2 hours of installation time.
There is nothing wrong with the inspection port itself, but I thought that there was room for further study on the metal stopper fitting like the attached spring. In that case I think that it is better to have a screw hole on the side.
