The Round Observation Port provides a safe and clear method to view the interior of a vessel. The port mounts easily to the vessel wall and protects from flying sparks. The standard housings are made of carbon steel. Fabrication in other metal materials is also possible. Four, six, and eight inch sizes are available from stock with a carbon or stainless steel housing. Other sizes are available upon request.
