Abstract: The present invention pertains to a removable clip that stabilizes a hanger mounted on a slatwall assembly formed by a number of horizontally aligned and uniformly spaced slats or boards. The upper and lower end of each slat has a lip with an inside surface, so that adjacent slats form a slot with a narrow outer portion and a wider inner portion. The hanger has an upper end that is inserted into an upper slot, and a lower end that hangs down near a lower adjacent slot. The stabilizing clip has a main body and an extending brace. The body is shaped to firmly snap fit into the lower slot. The brace extends upwardly along a middle slat to form a slot for receiving the lower end of the hanger and retaining it against the surface of the middle slat. In a second embodiment, the clip also includes a riser for supporting the lower end of the hanger and positioning the hanger so that its upper end more fully engages the inside surface of the lip of an upper slat.
