inspection chamber cover
Can I put a 450mm inspection chamber cover over a 470mm chamber
Advice from 5 local tradespeople
No a 450mm chamber cover cannot be put over a 470mm chamber
No a 450 mm inspection chamber cover will not fit over a 470 mm chamber
no it will not fit the next lids are 470mm and 500mm
No you cannot
This is a no ,the larger lid has to be on the top otherwise lid will drop into inspection chamber.
