Fiberglass Manholes

Product Details

Openchannelflow Fiberglass Manholes are a cost-effective solution to the need to measure or control piped flows below grade.

Openchannelflow offers a variety of different configurations to solve a variety of needs:

Where corrosion is a concern and a standard concrete manhole won’t due, Openchannelflow flow also offers standard flow through manholes.  These manholes can have pipe stubs for inline connection, or they can be provided as a drop-over “dog house” to go over the line.  Either style utilizes the same high strength / corrosion-resistant design!

At the core of each Openchannelflow Fiberglass Manhole is our ASTM D3753 highway rated manhole barrel.  The barrel is lightweight and yet still provides high strength, as well as excellent corrosion resistance.

Once integrated into one of our manhole structures above, the resultant unit is lightweight, watertight, easy to install, and requires virtually no maintenance.

Dig it!  Drop it! Done!
