One possibility might be inspection cover liners. You need to look in the
below-ground drainage catalogue in your local builders' merchants. They
are
used to line the hole between an inspection chamber and the cover above.


completely off topic aside: What's the difference between an inspection
cover and a manhole cover - and why?

Don't know for sure. Could be the same thing or could be that an inspection
cover is to allow visual access and a manhole cover is to allow someone to
climb in or out?

The hole underneath.

A manhole, as the name suggests, is (should be) big enough to enable
access by a person, ie you can climb into it. An inspection chamber is
just that for inspection and rodding access without climbing in.

Builders Merchants, note that they come in sections only about 9"
long.

Right, will investigate on this! 9" is a bit small but I could glue a couple
together, as long as the diameter is close then its not all to bad.

While im here, any one know about a 5" dia glass tube, such as a large 2pint
glass, straightish sides ?

Cheers,

thanks for the link! I take its 175mm is the height of it ? AS usual
screwfix leave off detail, I remember they couldn't tell me the dia of a
copper tube a year or 2 back!
