An electrical box extension includes a base having a first edge, a second edge, an inner wall, and an outer wall. The inner wall defines an aperture. An annular flange is disposed on the inner wall. The flange has first and second support surfaces. A first receiving section is formed between the first edge and the upper support surface. A second receiving section is formed between the second edge and the second support surface. The extension is reversible for extending the electrical box in either a partially or fully extended position.
