Abstract: A modular tack room which includes at least one wall hanger assembly and one or more hanging components. The wall hanger assembly includes an elongated vertical member which adjustably hooks over and grips the wall of a horse stall or trailer, and which has a plurality of receiving clips spaced along its length. A common mounting for a variety of hanging components includes a vertical mounting plate which fits downward within the receiving clip; two guide members, horizontally extending from the mounting plate, which are laterally separated by a space slightly greater than the width of the vertical tube to embrace the sides of the vertical member; and a lower support member positioned below the mounting plate to provide support against the vertical member.
