Available in six sizes, these Fire-Rated Convenience Doors allow access for passing items, including small items and paperwork, through wall openings into a lab or cleanroom, thereby reducing traffic in a critical space and eliminating the need for personnel to don proper cleanroom or lab attire.

Fabricated of 20-gauge 304 electropolished stainless steel, these doors are non-contaminating and stand up to most common cleaning and sterilizing agents. The fire-rated hatch door features a concealed hinge and 2" of fire-resistant fiber insulation. The door is mounted along the fire-rated wall, typically outside the classified space. A versatile mounting bracket is available to finish the wall cutout on the classified side of the wall (the cleanroom or laboratory) and accommodates wall thicknesses up to 4".
