Manhole Adjusting Rings

Adjusting rings (sometimes called extension rings) are used to raise a manhole cover so it's flush with a resurfaced roadway. Adjustings rings can reduce raising costs to as little as 20% of digging up the old manhole frame and resetting it to new grade. The adjusting rings can be replaced rapidly and are a permanent installation.
