A suction mounting device includes a unitary body of soft or rigid plastic having an interior and an exterior portion connected by a hinge. The exterior portion is movable between first and second positions about the hinge, the first position a pre-mounting position in which a gel material of the exterior portion contacts a mounting surface to form a cavity between the mounting device and the mounting surface, and a second mounting position in which the exterior portion is rotated about the hinge toward the mounting surface to create a larger cavity and a partial vacuum therein to hold the suction device to the mounting surface.
