A universal mounting assembly for the rapid mounting of an object to a stand device is described. The mounting assembly includes a body having a support surface, a front face and an opposed mounting surface, wherein the assembly is configured to mount to a support stand, such as a tripod. The body further includes at least two resilient, adjustable and articulating retaining arms disposed along at least two edges of the body, which allow for the sliding receipt of both the transverse width and longitudinal width, as well as the thickness dimension, of the object to be mounted. The back face of the body further defines at least two receiving ports extending from the support surface and oriented substantially perpendicular to each other. The mounting assembly is particularly useful in mounting a variety of camera phones, small cameras, and video phones to a stand device, such as a tripod.
