An attachment device for attaching office products or equipment to a panel wall that includes generally two elements: a locking member and at least one, and generally two, prong members. The locking member includes a base. Extended outward from the front face of the base is a key member for interaction with a keyhole on an office supply product. The key includes a stem portion and a knob portion and the stem portion is truncated so that the vertical dimension is smaller than the horizontal dimension. The key is inserted into the circular opening of a keyhole on an office supply product, is slid up into the slot portion of the keyhole and is then rotated 90° thereby locking the attachment device to the office product. The pins can be inserted into a panel wall thereby removeably attaching the office supply product to the panel wall.
