A mounting frame may be configured as a self-adjusting mounting frame that biases itself against a surface of structure. The mounting frame may be a component, for example, of a remote control device or a faceplate assembly. The mounting frame may be configured to bias a rear surface of the mounting frame against the surface of a structure. The mounting frame may include biasing members. Each biasing member may include an attachment portion and a pair of resilient spring arms that suspend the attachment portion relative to a perimeter wall of the mounting frame such that the attachment portion is spaced further from the rear surface of the mounting frame than locations where the spring arms extend from the mounting frame. The rear surface of the mounting frame may be defined by the perimeter wall.
