The diameter of this riser is 450mm and the height is 235mm. The riser can be cut to size as required using any standard fine-toothed saw. When installing risers you should always ensure that the integral rubber seal is located in the bottom groove of the riser. If the height of the 450mm inspection chamber exceeds 1200mm a CLKS499 chamber reducing ring is required to ensure compliance with building regulations. The FloPlast 450mm Large Inspection Chamber Riser and Sealing Ring allows you to extend the height of a large inspection chamber by 235mm to a maximum height of 1200mm with the standard frame and cover, and up to 3000mm using a 350mm reduced access frame and cover.
