Abstract
Abstract In the preferred form, an adjustable leg assembly including an externally threaded, vertically adjustable, leveling member, adapted to be received in a threaded portion in the base of the domestic appliance, and furthermore, having an internal bore for receiving a shipping bolt whereby the domestic appliance may be rigidly secured to the base of a shipping container by the shipping bolt and leveling member. Also, the leveling member has a counterbore adapted to receive a resilient plug when the shipping bolt is removed from the leveling member at which time a plurality of such adjustable leg assemblies may be vertically, axially adjusted with respect to the respective threaded portions in the base of the domestic appliance so as to level the domestic appliance when supported on the adjustable leg assemblies.
