Our Inclined Pivoted Turnbuckle Manhole Riser allows you to not only raise the lid, but also tilt the lid to match the new road crown. Edge milling operations remove asphalt at the curb, but not in the middle of the road, causing increase in the road crown. This method reduces cost, material, liability and time. Riser heights start at 1.5 in.
