The invention disclosed provides a rotary coupling mechanism that securely attaches common household fixtures to a wall. The invention is comprised of a wall bracket, a base bracket, a cam pin, and two mounting screws. Flanges on the base bracket rotationally engage flanges on the wall bracket and the cam pin inserted through the base bracket rotates to hold the flanges and secure the base bracket to the wall bracket. An alternate embodiment of the invention is comprised of a wall bracket and a base bracket having flanges with canted surfaces. A locking pin holds the brackets together after the flanges are rotationally engaged. For each application of the coupling mechanism, a decorative body conceals the apparatus. The decorative body is rigidly connected or pivotally connected to a decorative cap. The decorative cap retains various household fixtures such as paper holders, towel racks, or shelves.
