Access Manholes

Access Manholes are some of the most well-known products from Fairfield Industries. These manholes can range in size from 5” “Monitor Well” manhole cover to 60” manholes for access to large areas. Manholes typically are installed at grade level and provide access to underground equipment. Fairfield Industries manufactures manholes in various sizes, shapes and multi-port series with watertight access and custom configurations. In fact, due to aging infrastructure in many areas custom options are very popular and necessary due to wear, erosion and lack of standardized sizing.

Fairfield Industries is a leader in the United States in custom manhole manufacturing. We can build manholes for any application, and have a track record of high performance and timely delivery. If you are scoping a new project contact us for a quote.
