- a plurality of lower threaded bolt holes spaced apart on said sleeve flange;
- a lip extending upward from a perimeter edge of the sleeve flange;
- at least one imbed tab extending at a downward angle from the sleeve flange;
- a temporary sleeve cover plate being removeably attachable to said sleeve flange;
- a permanent upper assembly secured to the sleeve and sleeve flange;
- said permanent upper assembly comprises a raised ring having a perimeter wall and a raised ring flange extending perpendicularly from a lower edge of the perimeter wall wherein said raised ring flange attaches directly to said sleeve flange;
- and
- a raised ring cover plate secured to the raised ring.

A method for embedding an access assembly in a raised slab, said method comprising:
- pouring concrete around a tubular-shaped sleeve having an upper edge with a sleeve flange extending perpendicularly from the upper edge of the tubular-shaped sleeve;
- a lip extending upward from a perimeter edge of the sleeve flange to prevent concrete from covering the sleeve flange;
- securing a temporary sleeve cover plate to said sleeve flange to prevent debris from entering the sleeve;
- pouring said concrete around one or more imbed tabs wherein the one or more imbed tabs extend at a downward angle from the sleeve flange to further anchor the tubular-shaped sleeve within the concrete;
- removing the temporary sleeve cover plate and securing an upper assembly to the sleeve flange wherein said upper assembly comprises a raised ring having a perimeter wall and a raised ring flange extending perpendicularly from a lower edge of the perimeter wall;
- securing a raised ring cover plate to the raised ring;
- and
- applying a protective surface coating over said concrete, said lip, said sleeve flange and said raised ring flange.
