Manhole inflow protectors sit between the manhole frame and cover to help reduce, and in some cases prevent, surface water from entering the collection system. Each insert includes a vent hole to release a controlled flow if the protector becomes full, and a gasket seal is provided for proper seating against the frame. The unit is designed for straightforward handling and removal.
