A foot for adjusting the height of an appliance such as, for instance, a dishwasher or washing machine, provided with a threaded shank and a sprocket seated thereon for rotation relative thereto. The sprocket may be shifted between a first orientation in which the shank may be rotated while the sprocket is secured against rotation to adjust the height of the appliance by translatory movement of the shank and a second orientation in which the sprocket may be rotated and the shank is secured against rotation but is free to move axially.
