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.

1. A cover assembly for a floor box comprising: a base having a first end, a second end, and a central opening for accessing the floor box;a cover having a first end and a second end, and a dimension to close said central opening; anda hinge having a hinge body with a first end pivotally coupled to said first end of said base at a first pivot axis and a second end pivotally coupled to said first end of said cover at a second pivot axis, said second end of said hinge body extending in a longitudinal direction away from said second pivot axis and configured to contact said cover to limit pivoting of said cover with respect to said second pivot axis of said hinge body when said cover is pivoted in a closed direction. 2. The cover assembly of claim 1, wherein said hinge body has a longitudinal dimension extending between said first end and second end, and where said hinge body has a tab extending in said longitudinal direction from said second end, said tab being positioned to contact an inner face of said cover when said cover is pivoted to a closed position to limit the pivoting of said cover with respect to said hinge body. 3. The cover assembly of claim 2, 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. 4. The cover assembly of claim 1, wherein said first pivot axis is 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. 5. The cover assembly of claim 1, wherein said hinge body has a longitudinal dimension and where said first pivot axis is oriented in a first plane extending in said longitudinal dimension, and said second pivot axis is oriented in a second plane extending in said longitudinal dimension and spaced from said first plane, and a tab on a second end of said hinge body extending in said longitudinal dimension of said hinge body in said second plane, said tab being oriented to contact said cover during closing of said cover. 6. The cover assembly of claim 1, wherein said base further comprises a flange extending inwardly and defining a recess in said opening, a gasket on said flange for forming a seal between said base and cover, and a rigid member having a top surface oriented at a top face of said gasket at said first end of said base, said rigid member configured for contacting an edge of said cover at said first end of said cover during opening and closing of said cover with respect to said base. 7. The cover assembly of claim 6, wherein said cover has an inner surface with a recess at said first end of said cover oriented to mate with said rigid member of said base. 8. The cover assembly of claim 1, wherein said second end of said cover has 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. 9. The cover assembly of claim 8, wherein said slide latch has a first arm extending outwardly from the first side of said slide latch engaging said first detent and a second arm extending outwardly from the second side of said slide latch, and where said detents of said actuating member engage said arms to move said slide latch by pivoting of said actuating member. 10. 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 access 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. 11. A cover assembly for a floor box, comprising a base having a central opening for accessing said floor box, said base having a first end and a second end, and a flange extending into said opening, and a first rigid contact member having a contact surface spaced from a top surface of said flange;a cover having a dimension to close said central opening and contacting said contact 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 first end of said base at a first pivot axis, and a second end pivotally coupled to said cover at a second pivot axis, said cover being pivotally connected to said base and being configured where said first end of said cover contacts and slides on said contact surface during closing of said cover without contacting said top surface of said flange at said first end of said base. 12. The cover assembly of claim 11, wherein said first contact member extends upwardly from said flange and is spaced from a top face of said flange. 13. The cover assembly of claim 11, further comprising a gasket on said flange and surrounding said central opening, and said contact surface being oriented to contact said cover to resist wear on a top surface of said gasket. 14. The cover assembly of claim 13, wherein said base has a recess at said first end with an open side facing inwardly toward said central opening, and said first end of said cover has an edge received in said recess in said first end when said cover is in the closed position to prevent said first end of said cover from lifting upward from said base in the closed position. 15. The cover assembly of claim 14, wherein said recess at said first end of said base is defined by a hinge mounting bracket coupled to said base. 16. The cover assembly of claim 11, wherein said base has a first side and a second side extending between said first end and second end of said base, said first contact member positioned on said first side of said base at said first end to contact a first side of said cover, and a second contact member positioned on said second side at said first end of said base to contact a second side of said cover. 17. A cover assembly for a floor box, comprising: a base having a central opening for accessing said floor box;a cover pivotally coupled to said base and having a dimension to close said central opening;a sliding latch member coupled to said cover for sliding between a latched position and an unlatched position, said latch member having a first arm extending from a first side; andan actuating member pivotally coupled to said cover about a pivot axis, said actuating member having a first detent engaging said first arm, whereby pivoting said actuating member produces a sliding movement of said latch. 18. The cover assembly of claim 17, wherein said latch member has a second arm extending from a second side opposite said first side, and said actuating member has a second detent engaging said second arm. 19. The cover assembly of claim 17, wherein said cover is coupled to said base by a hinge having a first end pivotally coupled to said first end of said base and a second end pivotally coupled to said first end of said cover. 20. The cover assembly of claim 19, wherein said hinge has a tab extending longitudinally from said second end of said hinge and positioned to contact a bottom face of said cover to limit pivotable movement of said cover with respect to said hinge.
