I bought it because of the size decided by the fire prevention ordinance of the city. The thing itself is solid, I think that it is inexpensive and good. The mounting holes are 4φ and are open at the four corners. However, since there is 60 cm in the horizontal direction, I felt that it was easier to have a hole in the middle.
