A wall mountable frame structure for supporting appliances, entertainment equipment or other devices including peripheral horizontal and vertical structural beams with at least one intermediate vertical beam extending between and secured to the horizontal beams. A plurality of cladding panels removably attached to the vertical beams by way of a stud having a trapping member at its terminus which fits within a complimentary receiving portion of the vertical beams to secure the cladding panel to the vertical beams. A support bracket to be affixed to a wall and having mounting forks pivotally secured thereto is provided. A plurality of transverse mounting members are affixed to the vertical beams and are received by the mounting forks to secure the frame to a wall. The mounting forks are rotatable between first and second positions with the frame positioned away from the wall in the first position and against the wall in the second position. Each of the vertical beams defines a channel within which there is received a moveable fastener which is utilized to attach one or more pieces of equipment to the frame structure. The movable fastener frictionally engages the side walls of the channel to hold the fastener in position once it is adjusted to a desired location.
