Observation Ports

Observation ports are hexagonal nuts and gaskets with a clear viewing window, typically made of plastic. Observation ports may be installed in both rigid and flexible containers and may be applicable for some NEMA-rated enclosures.

The primary benefit of observation ports is that a viewing window provides for the quick and easy observation of a container or sealed enclosure’s contents without the need for opening the sealed container.

Most customers install two observation windows; one to look through and one to shine a light into. Sometimes they are placed on opposite sides of the container so it is easy to see light coming in from the opposite side. If you can see the light, it means the container does not have a load in it.

Observation ports can be used to safely observe objects within sealed enclosures in basic storage transportation to more dangerous environments including hazardous material holding tanks, furnaces, water tanks, and more.
