In my current drive I have 3 small concrete manholes. Removing the lids and measuring the inside dimensions of the brickwork beneath the cover I have:
2off 220mm square
1off 280mm square
Can you get recessed man hole covers that are this small that are still usable? A quick trawl of the web turned up these: http://buildingsuppliesdirect.co.uk/product....395 but I reckons they may look fugly with the big bits of tin in each corner?
Any others out there from merchants or the tinterweb?
because i was specifically after the type that don't have integrated keys, but hence have more metal showing, I found the manufacture then found the supplier, which turned out to be Sydenhams.
