These Morrison Bros Limited Access Environmental Manholes are offered in 8", 12", and 18" sizes, feature a clearly marked "Monitoring Well" designation which distinguishes them from a standard product fill manhole. These manholes feature a heavy duty cast iron cover and ring, a fuel resistant gasket to make them water resistant, and a heavy galvanized steel skirt to maintain an open area below the lid to work. Two stainless steel bolts are used to secure the lid, limiting access to the monitoring well below. These manholes are traffic rated at 8,000 lbs per tire and conform to H-20 ratings.
