Abstract: A self-leveling mounting assembly for mounting a mountable object on a vertical surface is described. The assembly includes: an engagement member structurally integrated in or securable to a mountable object, and providing a cavity; a fixturing plate adapted for securement to a vertical surface; and a retention member coupleable with the fixturing plate and with the cavity of the engagement member. The retention member includes first and second portions that are rotatable in relation to one another, with the first portion being fixedly positioned in relation to the fixturing plate, and with the second portion being positioned in the cavity to allow self-leveling movement of the mountable object on the vertical surface.
