| Our Manhole Adjusting Ring is installed under the utility casting on new construction or rehab of existing utilities. It replaces pre-cast concrete donuts or brick and mortar material. The Manhole Adjusting Ring is light weight and will not break. Freeze-thaw cycles do not affect it, thus providing a water tight seal that will last many years. Because the Manhole Adjusting Ring is made of solid rubber, it performs like a weight bearing pad on a bridge, eliminating vibration from traffic which deteriorates the cement substructure of the utility. Tapered sizes allow perfect adjustment to the roads crown or slope. |
