Underground Drainage Inspection Chamber Raising Piece - 320mm Round Chamber Access Riser

Q: is the diameter 320mm at both ends? Ive just bought one from toolstation and the top diameter was 330 so doesnt fit the cover

I do now the size but I bought the following cover and fitted Brand: CD352 4.8 out of 5 stars 8Reviews Future Build Supplies LTD Clark Drain CD352 1.5T Dual Lock Plastic Driveway 300MM Round Circular Manhole Cover & Frame Size with Frame is 390MM Suitable for 320mm Inspection Chamber & Riser

Q: Does this come with a seal on one end

They slot together. There is a rubber seal if that is what you need.

Q: How is this made smaller? The top cannot be cut due to losing the rim if cut and the bottom inch is a slightly wider diameter to allow it to slot over

If you get the drainage cover from Amazon it has a slightly longer piece on the bottom that slots into the pipe so the top rim is redundant ( I think but it was last year when we fitted them). This allow you to cut the drainage pipe down to the right size for the drive.

Q: Will this fit on my drain with an O/D of 330mm?

Seems to fit mine fine although it had to be reduced in order to level with the patio slabs. Hope this helps.
