Review: well made - did the job well and saved a small fortune , only downside did not come with the rubber seals for the risers but got around this with black silicone
Review: Good manhole - Good quality manhole for the price and went together ok. Only bone to pick with it has to be the fact that it doesn’t come with rubber seals on the risers which need to be bought separately (3 for each riser), also trying to figure out how to fix the lid frame to the riser, but otherwise it’s a good product.
