ABSTRACT:
A reusable concrete spacer sleeve comprises a substantially cylindrical body having a plurality of inwardly extending fins. The sleeve is placed over a vertical drain pipe prior to pouring a concrete floor. After the concrete has set, the sleeve is removed, leaving an annular space around the pipe for accommodating a flange. A lid may be fitted onto the sleeve to prevent debris or other foreign matter from entering the pipe or the annular space around the pipe.
