A mounting mechanism for attaching an article to a wall includes a first portion adapted to be attached to the wall and a second portion adapted to be attached to the article. The first portion includes at least one aperture formed therein, and at least one projection depending therefrom. In one embodiment, the first portion includes a tab depending therefrom. The second portion includes at least one aperture formed therein and at least one projection depending. To effectuate attachment of the article to the wall, the first portion and the second portion are engaged with one another. During engagement of the first portion and the second portion with one another, the at least one projection of the first portion is received in the at least one aperture of the second portion and the at least one projection of the second portion is received in the at least one aperture of the first portion to constrain movement of the first portion and the second portion relative to one another. In the embodiment including the tab, the tab constrains movement of the first portion and the second portion relative to one another during engagement of the first portion and the second portion with one another.
