This 200mm chamber riser is used in conjunction with our D800, D801 and D802 and D810 chamber bases to form a mini inspection chamber.
The diameter of this riser, which has an integral seal, is 300mm and the effective height is 200mm. The riser can be cut down to either 60mm,100mm or 150mm if required using any standard fine-toothed saw.
As 300mm chambers are narrow in nature, they are only practicable for use to a maximum invert depth of 600mm.
