A vertically adjustable hanger for supporting a dispenser for adding a chemical to a toilet tank on a vertical wall member of such toilet tank at a predetermined height to be selected by the user is described as including a bayonet member having means on its upper end for attachment to such toilet tank wall, and a channel means located on the chemical dispenser. The bayonet member further includes vertical adjustment means and, in a preferred embodiment, vertical control means located below its attachment means. The attachment means is rotatable between a predetermined substantially non-obstructive storage position and a hanging position, and when rotated from storage position to hanging position, increases the effective thickness of the dispenser. The channel means has a predetermined length, width and thickness and, in a preferred embodiment, includes locking means which cooperate with the vertical control means of the bayonet member to prevent vertical adjustment of the bayonet member except when the attachment means is in hanging position. The vertical adjustment means interacts with the channel means to provide vertical adjustability of the bayonet within the channel, whereby the vertical position of the dispenser may be adjusted as desired by rotating the attachment means into hanging position, and thereafter, advancing or retracting the bayonet member within the bayonet member within the channel means in a direction generally parallel to its length.
