Closeup of a fiberglass ladder in a Packaged Flow Metering Manhole.  Constructed from high strength fiberglass and reinforced with stainless steel rods in the ladder rung, these ladders are intended to provide easy access to the interior of our fiberglass manholes.  The ladders themselves are secured to the manhole wall through either fiberglass or stainless steel brackets.

The ladder is mounted in a Packaged Flow Metering Manhole which has a Parshall flume factory integrated.  Around the flume fiberglass benching is provided to give the operator a clean, safe, and secure area from which to work.

The manhole is provided with a domed fiberglass lid to provide excellent operator access.

The same ladder is used across all of our fiberglass manholes.
