A mounting system (100) includes a first surface and a second surface (300A, B). A device panel (106) can include at least first and second engaging members (204A, B). The first and second surfaces are sized and shaped to engage the first and second engaging members respectively, and the first and second engaging members move along the first and second surfaces. The first and second surfaces are sized and shaped so the reaction forces between the first and second engaging members and the mounting panel (104) cooperate to counteract the moment created by the center of gravity of the device panel to continuously immobilize the device panel at the plurality of angles relative to the support surface.
