Description
The chamber riser is used to build up the height of a compatible Kayflow 450mm inspection chamber system. It helps raise the chamber assembly closer to the finished ground level while keeping access available for inspection, rodding and maintenance.
This Kayflow UG1003 riser is part of the 450mm manhole chamber range for 110mm underground drainage layouts. It is designed for use with compatible Kayflow 450mm chamber bases, riser seals and cover options.
The riser is useful for domestic drainage, garden drainage, extensions, repairs and light-duty underground drainage work where extra chamber height is required.
Chamber Riser for 450mm Manhole Chambers
The chamber riser allows a compatible 450mm inspection chamber to be built up to suit the installation depth. It is used between the chamber base and the cover setup, or with other compatible riser sections where required.
Kayflow lists UG1003 as the 450 riser for its 450mm inspection chamber system. The same range includes the UG1005 chamber base, UG1007 riser seal, UG1001 round cover and UG2001 square cover.

Chamber Riser Connection
This chamber riser should be fitted as part of a compatible Kayflow 450mm chamber assembly. It helps extend the chamber height so the cover and frame can finish closer to the required ground level.
Before fitting, check that the chamber base, riser, seal and cover components are all compatible. Also, make sure the joint areas are clean and correctly aligned before assembly.
Kayflow states that silicone sealant should be used to fit the first riser to the manhole base and for subsequent riser-to-riser jointing. Always follow the site specification and manufacturer guidance.
Chamber Riser Installation Use
The chamber riser should be installed as part of a properly supported inspection chamber system. Correct bedding, backfill and chamber support help keep the assembly stable after installation.
Kayflow states that 450 inspection chambers can be installed to a maximum depth of 1200mm. Therefore, the final chamber depth should be checked before adding risers.
This product is a riser only. It is not a chamber base, sealing ring, cover or frame on its own.
Riser for 450mm Inspection Chamber Systems
This riser is useful for builders, groundworkers, landscapers and drainage installers working with 450mm inspection chambers.
It can be used when a chamber needs extra height to meet the finished ground level. However, the full chamber assembly must remain accessible after installation for future inspection and maintenance.
