Manhole riser

Feb. 22, 2011
American Highway Products Ltd.’s manhole riser is used to reduce cost and streamline the adjustment of utilities to the new grade when paving a road. Its unique pivoted turnbuckle linkage ensures a pressed-in bearing fit when installed. This pressed-in bearing fit enables installation before paving the road. The pivoted linkage will contract and expand the manhole riser ½ in., giving a full 1-in. diametric variance, thus allowing the flexibility to work on different diameter frames. The risers start at ¾-in. rise and go up in ¼-in. increments.
