Precast Grade Rings can be added at vault and manhole access openings to allow the manhole cover to reach grade level.  They come with handle loops cast in for easy maneuverability.   Milan Vault's Precast grade rings allow for height adjustability of access openings and are available in a variety of heights for increased flexibility during vault and manhole installation.
