The UG Inspection Chamber Riser 320mm is designed to extend the height of underground inspection chamber systems, allowing the chamber to be brought up to the required ground level. It is used in conjunction with compatible chamber bases, covers, and frames to complete a full drainage access system.
Manufactured from durable plastic, the riser is suitable for below-ground use and provides resistance to moisture, ground conditions, and general wear. It is commonly used in domestic drainage systems and light-duty applications.
With a 320mm diameter, the riser is designed to fit securely onto compatible 320mm inspection chamber bases, ensuring a stable and aligned connection. Multiple risers can be stacked where required to achieve the desired chamber depth, depending on installation requirements.
The riser provides vertical extension within the chamber system, maintaining access for inspection and maintenance of underground pipework. It is suitable for use in both foul and surface water drainage systems.
Installation is straightforward, with the riser fitting directly onto the chamber base and additional risers if required. It can be cut to size on site where necessary to achieve the correct height.
The riser is designed to be used with suitable chamber covers and frames, selected based on the required load rating, typically for pedestrian applications.
The UG Inspection Chamber Riser 320mm provides a practical and reliable solution for adjusting chamber height within underground drainage systems.
