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 3, wherein said base has a top face, said cover having a top face aligned with and coplanar with said top face of said base when said cover is in the closed position, andsaid top face of said cover lying flat against said top face of said base when said cover is in an open position. 5. The cover assembly of claim 4, wherein said first end of said hinge body is pivotally connected to said base at a pivot axis positioned below said top face of said base, and where said second end of said hinge body is positionable with respect to said base between a first position below said top face of said base and a second position above said top face of said base. 6. The cover assembly of claim 2, wherein said hinge body has a transverse dimension and where said first pivot axis is spaced apart from said second pivot axis along said longitudinal dimension and along said transverse dimension of said hinge body. 7. The cover assembly of claim 6, wherein said tab on said hinge body extends in said longitudinal dimension of said hinge body in a plane spaced from said first pivot axis. 8. The cover assembly of claim 1, wherein said base further comprises a recess defining said opening, said recess having a ledge, a gasket support on said ledge for forming a seal between said base and cover, and a raised surface spaced from said ledge and positioned at a top face of said gasket, said raised surface configured for contacting said cover during opening and closing of said cover with respect to said base. 9. The cover assembly of claim 8, wherein said hinge body is coupled to a first end of said base and to a first end of said cover, said raised surface being positioned at said first end of said base and defines a slide surface for an edge of said cover during opening and closing of said cover. 10. 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, 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. 11. The cover assembly of claim 10, 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. 12. The cover assembly of claim 1, wherein said biasing member includes a compression spring washer positioned between said cover and said access door to apply an axial force against said access door. 13. 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, and at least one slide member having a slide surface;a gasket positioned on the base;a cover having a dimension to close said central opening and contacting said slide surface 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. 14. The cover assembly of claim 13, wherein said base has a flange extending into said central opening and spaced from a top face to define a recess, andsaid slide member extends upwardly from said flange to define said slide surface spaced from a top face of said flange. 15. The cover assembly of claim 14, wherein said gasket is positioned on said flange surrounding said central opening, and said slide surface being substantially flush with a top surface of said gasket. 16. The cover assembly of claim 15, wherein said base has a first end coupled to said hinge body, and said slide surface positioned at said first end of said base to contact a first end of said cover during opening and closing of said cover. 17. The cover assembly of claim 16, wherein said base has a first side and second side extending between said first end and second end of said base, and a first slide surface on said first side of said base at said first end and a second slide surface on said second side at said first end of said base, andsaid cover having a first edge at a first end of said cover to slide on said slide surface during opening and closing of said cover. 18. A cover assembly for a floor box, comprising: a base defining a central opening for accessing said floor box, said base having a flange spaced from a top face of said base and extending into said central opening; a cover having a dimension to close said central opening and to mate with said flange; and an access door coupled to said cover to pivot into said central opening: and a hinge having a hinge body coupled to said cover and said base to pivot said cover between an open position where said cover is substantially parallel to said base and a closed position where said cover is received in said central opening; wherein said flange has a first slide member on a first side at a first end of said base and a second slide member on a second side at said first end of said base, said first and second slide members defining first and second slide surfaces for contacting a first end of said cover during opening and closing of said cover. 19.
