Abstract: A bracket for mounting a device to support structure has (i) a first side and (ii) second and third sides that extend perpendicularly from opposite edges of the first side in the same direction, such that the second and third sides are parallel to each other. The bracket supports a first mounting configuration in which the first side is attached to a face of the device and the second side is attached to a plane of the support structure such that the side of the device is perpendicular to the plane of the support structure. The bracket also supports a second mounting configuration in which the third side is attached to the face of the device and the second side is attached to the plane of the support structure such that the face of the device is parallel to the plane of the support structure.
