Abstract: The line cord and handset cord plugs of a telephone base are fixedly mounted in jacks within exterior cavities of the base bottom. The baseplate is detachably secured to the base by the feet which are rotatable. In addition to locking the plugs into their cavities, the baseplate mass serves as a convenient vehicle for imparting added weight for stability to the base.
