Hi I have seen a picture on the internet of an access chamber I am trying to re create. as seen in the picture it is a hinged concrete cover but I am confused on how the hinging works. when this cover is closed, there is only a 3mm gap all round between the frame and cover edge. as this strut needs a sort of hinge turning point, does anybody have any ideas how this is achieved and where the point is.
thanks in advance
