A utility box having a housing, and a ring that forms a hole that receives an attachment from a cover. A fastener retention piece has a first recess in a first surface, a second recess within the first recess, and a third recess in a second surface. The first and second recesses retain fasteners when the first surface is adjacent a lower surface of the ring. The third retaining recess retains a fastener when the second surface is adjacent the lower surface of the ring. The fasteners secure the attachment depending from the cover, and the recesses prohibit complete rotation of the fasteners. |
