This is a box of 20 Leviton #PSC8-R red sectional wallplates. These appear orange in the photos - they are definitely red. It is a center section with a standard duplex receptacle opening. Sectional wallplates are used in custom applications to "build" the right wallplate for a special installation. These are made of a tough unbreakable thermoplastic material for high impact resistance. Each is separately packaged with matching mounting screws.
