#CMT# #/CMT# The device has a set of compensating rings (1) made of plastic. Each compensating ring has a set of recesses provided at a lower surface, and a set of heels provided at an upper surface. The recesses ensures sufficient mortar to be provided between bearing surfaces of the rings and/or a channel pit opening and a channel manhole cover, where each recess is filled with mortar. #CMT#USE : #/CMT# Device for compensating height of a channel manhole cover on a channel pit. #CMT#ADVANTAGE : #/CMT# The design of the device enables the device to avoid incorrect remarks and to implement reconstructions in an economical manner. The recesses ensures sufficient mortar to be provided between bearing surfaces of the rings and/or the channel pit opening and the channel manhole cover, where each recess is filled with mortar, thus enabling easy handling of the device due to light material of the compensating rings, enabling the rings to be turned, rotated or lifted into all directions without large efforts and enabling complete, fast and economic filling of the recesses with mortar, and hence enabling complete mortar-mix. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a compensating ring. 1 : Compensating rings. |
