From Floplast
This 300mm chamber riser is used in conjunction with our D800, D801 and D802 and D810 chamber bases to form a mini inspection chamber. As 300mm chambers are narrow in nature, they are only practicable for use to a maximum invert depth of 600mm. All of our inspection chamber components are sourced from reputable supplier partners who are leaders in the UK market such as FloPlast. Inspection chambers are a vital part of the underground drainage system, whether it be residential or commercial. They are necessary to provide access into various key points of the underground drainage system.
