A bracket for attaching an advertising unit to a support structure includes a metal plate having multiple cavities. A first bite member extends into a first cavity and is oriented to engage the support structure in a first bracket orientation when the support structure is received in the first cavity. A second bite member extends into a second cavity and is oriented parallel to the first bite member. The second bite member engages the support structure in the first bracket orientation when the support structure is also received in the second cavity. A third bite member extends into a third cavity and is oriented to engage the support structure in a second bracket orientation. A fourth bite member extends into the third cavity and is oriented parallel to and oppositely facing the third bite member. The third and fourth bite members engage the support structure in the second bracket orientation.
