  • Application
  •  

The Model TG-MH-18 18" Manhole is designed to set flush on a concrete pad at grade and provide access as required to equipment installed on an underground tank, such as tank gauging and leak detection equipment. Because the manhole is not attached to the tank, it eliminates the possibility that the weight of a vehicle might be transferred to the shell of the tank. The assembly consists of cast iron body ring, 3/8" steel cover, and a 12" skirt. The bottom is open, allowing water to run off and away from tank monitors or other delicate components.

NOTE: The manhole is not designed for access to tank fill pipes.
