*Conveyor chute inspection doors are not recommended for use in applications where the material-flow path may directly impact the door. Lined doors are not intended for use in hopper applications, where the depth of collected material may exceed the installed elevation of the door opening. These inspection doors should never be installed in any part of a potentially pressurized containment vessel.
