A cover assembly for a floor box includes a base with a central opening and a cover pivotally connected to the base by a hinge member. The hinge member has a hinge body with a first end pivotally connected to the base for pivoting with respect to the base and second end pivotally connected to the cover for pivoting with respect to the cover. A tab extends from the second end of the hinge body to contact a bottom surface of the cover to limit pivoting movement of the cover with respect to the hinge body. A slide surface is provided on the base that contacts an end of the cover during pivoting movement of the cover to prevent wear on a gasket with the opening of the base.

The cover assembly of claim 1, wherein said cover has a first end pivotally coupled to said hinge body and second end having a latch assembly, said latch assembly comprising:a slide latch coupled to said cover for sliding in a plane of said cover between a retracted position and an extended latching position,an actuating member pivotally coupled to said cover, said actuating member having a pivot axis parallel to said plane of said cover and a first detent engaging a first side of said slide latch and a second detent engaging a second side of said slide latch, whereby pivoting said actuating member causes sliding movement of said slide latch. 10. The cover assembly of claim 9, wherein said slide latch has a first arm extending outwardly from a first side of said slide latch engaging said first detent and a second arm extending outwardly from a second side of said slide latch, and where said detents of said actuating member engages said arms to pivot said slide latch by pivoting of said actuating member. 11. The cover assembly of claim 1, said cover further comprising a cord access opening, andan access door pivotally coupled to said cover to close said cord access opening, said access door having two opposing pivot pins pivotally coupled to said cover to pivot said access door between a closed position to close said egress door and an open position, a compression spring washer on at least one said pivot pin and positioned between said cover and said access door to apply an axial force against said access door to retain said access door in said open position and said closed position. 12. The cover assembly of claim 1, wherein said hinge body has a top face and a bottom face extending in said longitudinal dimension between said first longitudinal end and said second longitudinal end, and where said tab extends along said bottom face of said hinge body in said longitudinal dimension. 13. The cover assembly of claim 12, wherein said first pivot axis of said hinge body is oriented in a first plane extending in said longitudinal dimension, andsaid second pivot axis of said hinge body is oriented in a second plane extending in said longitudinal dimension and spaced from said first plane. 14. A cover assembly for a floor box, comprising a base defining a central opening for accessing said floor box, said base having a first end and second end, a flange extending into said central opening and spaced from a top face of said base to define a recess, and a first raised member at said first end and extending upwardly from said flange, said raised member having a top face defining at least one slide surface in said opening at said first end;a gasket on said flange and surrounding said central opening;a cover having a dimension to close said central opening and contacting said top surface of said raised member during opening and closing of said cover with respect to said base; anda hinge having a hinge body with a first end pivotally coupled to said base at a first pivot axis, and a second end pivotally coupled to said cover at a second pivot axis. 15. The cover assembly of claim 14, wherein said raised member is provided on said flange extending into said central opening and spaced from a top face to define a recess, andsaid raised member extends upwardly from said flange to define said slide surface spaced from a top face of said flange and said raised member being positioned next to said gasket. 16.
