Can anyone tell me if the openings on manholes have been increased to 680? Been a while since i brought the brickwork up on one and thought the entry looked larger and on measuring it, it was indeed 680 ???

most of the rectangles we do are 600 by 450 internal
maybe its a new EU thing?

Always been 600x600 on manholes, IC chambers may be smaller openings. Think it might be new regs' for confined space entry by tripod and harness maybe ???

.......That's what I'm trying to find out Dave.
Last time I bricked one up they were 600x600.
Can't seem to find the information but I am using my phone, will have good look when I'm at home.
Thanks guys'.
