Patent ID: 6886190

Claim:
An apparatus for alignment of underlying slab-mounted drain apertures with overlying drain openings in finished surfaces comprising: a substantially planar center section having a top surface and a substantially planar bottom surface, a perimeter edge; and a center axis running therethrough; said center section having a drain opening communicating between said top surface and said bottom surface, said drain opening having a central axis; said drain opening positioned in said center section such that said center axis of said center section is spaced from said central axis of said drain aperture; a substantially planar surface layer having a substantially planar bottom surface and substantially planar top surface, said surface layer adapted for overlay upon a substantially planar slab surface extending continuously outward from a substantially flush mounted drain aperture, a formed opening, said formed opening defined by a cutout in a surrounding section of said surface layer communicating between said top surface and said bottom surface of said surface layer; said perimeter edge of said center section dimensioned to engage within said formed opening; and said center section rotatable when positioned within said formed opening with said bottom surface of said center section and said bottom surface of said surface layer both supported by said slab surface, to thereby position said drain opening substantially inline with said drain aperture, whereafter said bottom surface of said center section is affixable to said slab surface in a substantially contiguous mount.
