T1R/625

Compensation rings with edge protecting against movement used to adjust height of concrete sewage manholes with DN625 internal manhole opening diameter made according to DIN 4034. They allow to correctly refer the diameter and height of a sewage manhole and install manholes with external manhole plate diameter up to max. Ø805mm (e.g. DIN 19584). They are elements compatible with concrete compensation rings used to construct tight surface finials, and alternating finials without mortar. They are also installed on T3/600, T3/615, and T3/680 relief cones in plastic sewage manhole systems with DN600 manhole opening as an additional height adjustment element. Elements of surface finials for self-levelling manholes constitute as a basis for installation of leading adapters from TXS group.
