Order a Manhole Riser 320/450mm for Underground Drainage and Sewer Systems.
For use with our budget manhole base range, these risers come with a pre lubricated sealing ring already installed which sales both time and money. These manhole base risers carry a British Kitemark to prove that they’ve been tested to above and beyond the standards required. EasyMerchant’s budget manhole risers are made in the UK and have been selected due to their high quality and low cost. The only reason these manhole bases are cheaper is because they’re not often specified as they do not carry the usual house hold brand name – however they have been tested to perform at the same standard as these brand name manhole bases.
Inspection chambers are an important part of any drainage system, and the risers are an important part of the inspection chamber. As such we have made sure that we select only the best sewer pipe products that carry the necessary accreditations and are available to you at an amazing price.
The risers are 140 and 235mm high for the 320 and 470mm versions and are manufactured in polypropylene.
We aim to dispatch all orders for next day delivery, however please allow 2-3 days as a precaution.
