Flexible metal conduit will be allowed, in lengths not to exceed 1.2 m (4 ft.), to connect physically adjustable equipment and devices allowed to be in these fabricated ducts and plenum chambers. The connectors used with flexible metal conduit will effectively close any openings in the connection. Equipment and devices will be allowed within such ducts only if necessary for the direct action upon, or sensing of, the contained air. Where equipment or devices are installed and illumination is necessary to facilitate maintenance and repair, enclosed gasketed-type luminaries will be allowed.
