Unused openings

Can anyone post the text of the article that addresses unused openings. My NEC on CD is not working and I won't get my replacement until Monday.

110.12(A) Unused Openings. Unused openings, other than those intended for the operation of equipment, those intended for mounting purposes, or those permitted as part of the design for listed equipment, shall be closed to afford protection substantially equivalent to the wall of the equipment. Where metallic plugs or plates are used with nonmetallic enclosures, they shall be recessed at least 6 mm (? in.) from the outer surface of the enclosure.

Thanks
I knew it didn't say anything about the plugs being listed.
