        Depends. The cover is resting on the inside lip which prevents moisture getting in. Ie. this cover is actually significantly bigger than the hole it’s covering.

        Eg. if this cover is 25x25, but it’s covering a hole which is less than 18x18 (c=25.5), it’ll be quite hard to drop the cover in.

          I think you’re misunderstanding. Yes, it cannot fit in when it’s angled properly to fit into the hole. However, if you angle the plate 45 degrees and lift one end of the plate, it will fall into the diagonally. That’s why manholes are round shaped. There is no angle for a round cover to fall into the hole itself.
