Tilt the Utility Lid to Match the Crown of the Road with Our Inclined Manhole Riser.

Our Inclined Manhole Adjusting Riser Rings feature a turnbuckle linkage pivoted at each end to provide the ultimate means to expand a manhole riser. This construction allows efficient application of a screw. A 60 lb. force applied 7’’ from the center of the pivoted turnbuckle exerts a 5,600 lb. tangential force in the Manhole Adjusting Riser Rings that will be bent to fit the out of round, worn manhole opening.
